Danny Phantom

Paulina indirectly saved Sam from being possessed by Kitty, by pushing and ticking Sam off.

Apparently, Sam is pretty strong since she was able to mak a dent in a locker and crush a napkin holder.

Insight Digital Description: In exchange for Paulina's pledge of silence in regards to Danny's secret alias, Danny becomes her boyfriend, a role that he cherishes until he discovers that Paulina also has something to hide.

Apparently, ghosts can be attracted to humans since Johnny was checking out human girls.

Apparently, Danny now has the ability to hit someone while he is intangible.

The picture of Sam, Tucker, and Danny that was in Danny's locker (before he replaced it with a picture of him and Paulina) is the same picture Wulf was carrying in the previous episode, "Public Enemies."

Nickname(s) Dash Gives Danny: Fenturd.

Apparently, Tucker cannot swim, or is learning how to swim, since he is wearing floatation devices around his waist and on his arms at the Floody Waters water park.

Look Hard: In Paulina's Inviso-Bill love shrine, there are: 1) Two Danny Phantom action figures hanging from her locker. 2) Six pictures of Danny Phantom. 3) A pink poster that says "Paulina (picture of a heart) Inviso-Bill." 4) The Ghostbusters symbol. 5) Two pink lit candles. 6) A pink pot with three roses. 7) Two purple hearts. 8) A purple mirror. 9) A purple banner that says "CHS."

Look Hard: In the locker of the blonde boy who screamed "Nooooo!" after Paulina (overshadowed by Kitty) openly declared that she and Danny were dating, there is a love shrine to Paulina, which is very similar to Paulina's shrine to Inviso-Bill near the end of the episode. In that locker, there is: 1) A heart-shaped disco ball. 2) Two lit candles. 3) Five pictures of Paulina (one of them is in a heart shape). 4) Two posters that say "Paulina." 5) A poster that says "Love." 6) A poster that says "Always." 7) A poster that says "Forever."

Look Hard: Nathan (who officially debuts in "Reign Storm") makes two short cameos in this episode. The first one is at the lunch table on the right in the cafeteria when Danny says, "I'm really happy that you're cool with this, Paulina." and the second one is at Nasty Burger, during the scene where Sam and Tucker are simultaneously complaining about Star and Kwan, Nathan can be seen sitting at a table on the right, although he is completely blue.

Apparently, Kwan desperately wants to fit in a social group, since he was considering the chess club, after he was temporarily kicked out of the popular group and Sam and Tucker did not want him in theirs either.

The bowling alley that Danny, Paulina, Star, and Tucker were at is called "Amity Park Lanes."

Kwan and Star are the second and third members of the popular kids that were thrown out of the group, the first member was Valerie in "Shades of Gray," however, she was not let back in at the end of the episode, like Kwan and Star.

It is hinted in this episode, that ghosts have the ability to tap into the memories and the personality of the person they overshadow.

Danny does not catch a ghost in the Fenton Thermos in this episode.

Paulina is the second human who has been attracted to a ghost. The first one was Jazz in ""13"."

Tucker reveals that Star is Paulina's satellite, "the marginally attractive girl who always orbits around the popular girl." However, in the numerous speechless cameos that she made in previous episodes, the only time she was near Paulina was in "Splitting Images."

Look Hard: At the beginning of Kitty's flashback, there is a billboard that says "Amity Park, A Nice Place to Live," which is a variation of the billboard that appeared at the beginning of ""13"," "Welcome to Amity Park, A Safe Place to Live."

Apparently, Kitty must have somehow got her red jacket and purple scarf back, since she is wearing it in this episode, although her ring is nowhere in sight.

References to ""13"" were made in this episode.

Look Hard: During the montage, in Kwan's locker, there is a picture of Kwan and Dash in their football uniforms. Dash's number is 4 (which was first revealed in "What You Want") and Kwan's number is 10.

This is the first episode to feature a musical montage.

After making numerous speechless cameos in previous episodes, Star officially debuts in this episode.

Star seems to really like Tucker, since she still wants to be friends with him, even though she is with Kwan now.

This episode marks the third time that Danny is temporarily popular, the first time was in "Attack of the Killer Garage Sale" and the second time was in "Splitting Images" (although Poindexter was in Danny's body).

After it was presumed in "Shades of Gray," it is confirmed that Valerie and Kwan has officially broken up and Kwan is now dating Star.

We learn that the name of the bookstore that Sam mentioned in "Fright Night" is called "Skulk and Lurk Books," but she cannot go there anymore, courtesy of Kwan.

We learn that being a "cool kid" in Casper High comes with a "Cool Kids Membership Packet" that says "A-List" on it, a nerd that does the cool kid's homework, and a hall pass card, that can get that cool kid a free yogurt after the hall monitor stamps it ten times.

Running Gags: 1) Tucker talking about giving a girl mouth-to-mouth resuscitation. 2) The blonde boy that loves Paulina screaming "No!" after seeing her with Danny and after hearing that she's going out with Danny. 3) Sam claiming that she is perfectly happy with Danny being together with Paulina, and then physically taking out her anger on objects. 4) A person telling somebody not to talk to a person because they are nowhere near cool enough. 5) Kwan unintentionally making Sam and Tucker miserable. 6) Star bossing Tucker around. 7) Someone suggesting that someone else "should play it close(r) to the vest." 8) Someone asking if something is "like a..." and then someone else replying "not like a... a..."

We learn that Sam hates the sun, and in "Control Freaks," Sam reveals that she considers herself "a creature of the night."

Opener: Danny, Sam, and Tucker are at the Floody Waters water park, and Tucker is eager to give girls mouth-to-mouth. After Sam leaves to go to the bathroom, Johnny 13's Shadow appears. Danny accidentally runs into Paulina and Star, who make a joke about him. He ignores it, goes ghost, and battles Shadow. He defeats Shadow and after he changes back into human mode, he sees that Paulina was watching him.

The name of the nerd who wanted to know if Skulker was done using the computer in "One of a Kind" is revealed to be named Mikey.

Major Human Debut(s): Star.

Although Paulina currently has no feelings for Danny Fenton, she is now madly in love with Danny Phantom, whom she knows as Inviso-Bill.

Johnny 13 has attached an un-named Fenton gadget to his motorcycle. It allows him to drive in and out of the Ghost Zone when he pleases. It creates a portal in the dimensions that allow him to go through. However, Danny destroyed it and trapped him in the Ghost Zone.

This episode's title screen marks the second time Danny is seen in human mode. The first time was in "Teacher of the Year."

Star is very similar to Veronica from The Fairly OddParents. They are both "satellites" to the most popular girl in their schools. In addition, Star's voice and personality seems to mirror Veronica's.

Sam suggests that Paulina might not believe what she saw and forget about it, which is exactly what they think happened to Jazz in "My Brother's Keeper."

Danny Phantom is now known as "Inviso-Bill" all through Amity Park.

After a long absence since "Prisoners of Love," The Box Ghost finally returns, making a small appearance.

A portion of this episode takes place in a water amusement park called "Floody Waters."

Title Screen Caption: "Heart Aching Terror!"

Look Hard: Danny goes ghost in the "Floody Waters" water park near a map of the place. Some of the attractions include "Terror Mountain," "Typhoon Bay," "Tsunami Bam," and ten shops.

No new named Fenton inventions were introduced in this episode.

Jazz, Maddie, & Jack are all absent in this episode.

Main Villain(s): Johnny 13 & Kitty.
