Danny Phantom

Title Picture: Wulf slashing a wanted poster of Danny.

This is the first time Danny calls out the name of one of his attacks (Go ghost stinger).

Danny Phantom saving Paulina seemed to foreshadow her falling in love with him in the next episode.

This marks the most number of times Danny's ghost sense goes off in a single episode.

This episode marks the first time Danny's ghost sense goes off in his ghost form, and apparently, it is stronger then, since it sensed Walker and his henchmen while they were still overshadowing humans.

Mayor Montez (while possessed by Walker) gave Jack privileges to make all ghost policing and security decisions, while Maddie just became the Mayor's security advisor.

According to Bullet, all the escaped prisoners (except for Danny) have been captured, which means even the Lunch Lady Ghost, Skulker, Technus, and Desiree have been captured.

Additionally to making portals to Earth, Wulf's claws are also capable of removing ghosts out of people's bodies.

Maddie reveals that she's a ninth degree black belt.

We learn that the Fenton RV's ghost shield only lasts for fifteen minutes and that it's not totally impenetrable since Wulf was able to "drill" himself inside it.

We learn that Danny's ghost sense goes awry when there are many ghosts around him.

This episode marks the second time that Jack and Maddie have mistaken a human for a ghost; this time it's Mr. Lancer. The first time was Jazz in "Mystery Meat."

Apparently, when Danny was imprisoned in "Prisoners of Love," he took a mug shot and was ironically smiling in the picture.

This is the first massive city-wide ghost invasion in the history of Amity Park.

It is revealed that Maddie invents new types of cookies, such as "butterscotch caramel apple doodles."

Look Hard: The billboard that Danny throws Paulina, who was overshadowed into said, "Say yes to Amity," with Mayor Montez's face on it.

Look Hard: On the door of the police car in the opener, there is a logo that says, "APPD" (probably standing for Amity Park Police Department). More police cars with that same logo are shown again in "Control Freaks."

The Ghostkateers consisted of Jack, Maddie, Dash, Kwan, and Paulina.

The three ways that the Casper High students' freedom was restricted were: 1) Students are to have no contact with the ghosts. 2) All students will be escorted to their homes directly after school. 3) All students are to have a 9:00 PM curfew.

It is revealed that when a ghost overshadows a human, it is possible for ghosts to retain the human's original voice and eye color.

After it was hinted by Vlad in "Bitter Reunions," it is confirmed that ghosts are still able to fly and become intangible, even when they are inside a human's body; because of this, possessed humans are unable to get past an anti-ghost shield.

The main characters that were possessed by Walker and his guards were Dash, Kwan, Paulina, Mr. Lancer, and Principal Ishiyama.

Running Gags: 1) Jack interrupting Maddie for a cookie. 2) Maddie saying, "Hi, sweetie!" to Danny through a bullhorn. 3) Jack trying to use the Fenton Fisher, but can't, since it's tangled up.

The woman who explained why Tucker was excused from the Cramtastic session in "Fanning the Flames" is revealed to be the principal of Casper High, Principal Ishiyama.

According to Maddie, ghosts are not actually dead people, but rather "manifestations of ectoplasmic energy and post-human consciousness."

Look Hard: Nathan (who does not officially debut until "Reign Storm") makes a cameo in this episode: when Jack asks Maddie for some butterscotch caramel apple doodles, Nathan can be seen on the far left, although he is completely purple.

Major Human Debut(s): Tucker's mom, Tucker's dad, Mayor Montez.

Look Hard: In the auditorium during the assembly, there are many posters of the Amity Park mayor and his name is revealed on the posters to be "Mayor Montez."

Wulf is the second ghost that befriends Danny.

This is the second episode to begin in the Ghost Zone. The first was in "Fanning the Flames."

Opener: Walker's henchmen round up the last prisoner who tried escaping the prison. Walker turns to a wolf-like ghost named Wulf. Wulf tries to claw into the real world, but Walker stops him. Walker explains that he wants revenge on Danny by turning his world into the prison he escaped. He then makes a deal to let Wulf go if he brings his henchmen into the real world and cause havoc. Wulf agrees, and the henchmen go to the real world and wreck Amity Park.

This marks the second time that Danny uses his ectoplasmic blasts to remove ghosts from people's bodies. The first time being in "What You Want."

Look Hard: Star (who plays a much larger role and officially "debuts" in the next episode, "Lucky in Love") makes five cameos in this episode. The first one is on the TV, when Shelley Makamoto was talking about the ghosts attacking Amity Park. In the flashes of the scenes from the prior night: Star can be seen on the television running away from one of Walker's guards. The second one is when Danny, Sam, and Tucker leave their seats in the assembly to sit in the back of the auditorium: Star is on the left of Jazz. The third cameo is when the camera focuses on the kids saying, "Yikes, it's a ghost attack!": Star can be seen screaming it while standing. The fourth one is when the kids are eating their lunch in the anti-ghost shield: Star can be seen at a table on the far left eating mashed potatoes with a boy. The fifth and final cameo is when the people are running away during the town meeting: Star can be seen running right before Walker (in Mayor Montez's body) phases Danny through the floor.

It is hinted that Danny can be put in the Fenton Thermos, even though he is half ghost. When the principal and Dash (possessed by Walker and a guard) held the Fenton Thermos at Danny, charging it up, Danny looked scared.

This is the first episode in which Maddie successfully fights a ghost on her own.

References to "Prisoners of Love" were made in this episode.

This marks the second time Jazz actively helps Danny in his ghost fighting. The first time was in "My Brother's Keeper."

Danny Phantom gains a new mortal nemesis in his mother - Maddie Fenton. His first was Valerie Gray from "Shades of Gray."

The character Baby Face Boyle is based on producer and art director of the show, Bob Boyle. He also made a brief appearance as a prisoner in the Ghost Zone, in the episode "Prisoners of Love." The character has Bob's head, a wolf's teeth, and Frankenstein's body.

Paulina is the only known citizen besides Sam, Tucker, and Jazz who know that Danny's a good ghost and doesn't mean any harm.

Danny's "going ghost" cry finally returns, it was last used in "Bitter Reunions."

Title Screen Caption: "It's Fang-Tastic!"

Look Hard: When Danny fights an overshadowed Dash near the Nasty Burger in one scene, there's a car that has a license plate that reads "040304," the date that Danny Phantom premiered on Nickelodeon (April 3rd, 2004).

Look Hard: When Sam is holding a newspaper near the end of the episode, you can see the name "Amity-Park-Angle," it is probably the official Amity Park newspaper. The headline read "Public Enemy Number One."

The Fenton Ghost Fisher from "Parental Bonding" and the Fenton RV from "Bitter Reunions" both return. The Fenton RV is destroyed and the Fenton Fisher was tangled throughout the whole episode.

Introduced Ghost Power(s): Go Ghost Stinger.

Featured Named Invention(s): Fenton Ghost Bazooka, Anti-Ghost Shield.

Major Ghost Debut(s): Wulf - A werewolf-like ghost that became Danny's friend. He speaks very little English. Wulf sacrificed himself to save Danny from being sent to the Ghost Zone. He has the power to make a portal to the real world by using his claws. Bullet - He seems to be Walker's head henchman. Not much is known about him, except that he is just as strict as Walker and also after Danny.

Wulf mostly speaks a language called Esperanto. Walker's the only one who can understand this language in any way. Tucker also seems to understand his language a bit.

Main Villain(s): Walker.
