Fooly Cooly

The two guitars Noata summons are a Gibson Flying V and a Gibson SG bass.

When Naota comes out of Canti with Atomsk's power you can see the outline of the bandage on his head which is then replaced by the Atomsk symbol. Then, when he turns back to normal the bandage is gone.

When Naota gets a soda, he's wearing a hat. When he runs into Amarao, he's not. It's unlikely that he would take it off and put it in his back pack on the way home for no reason.

Though both Haruko and Amarao refer to Atomsk's instrument/weapon as "Atomsk's Gibson EB-0... 1961 model", it looks a lot closer to the Epiphone EB-0 that's sold today.

If you look carefully at the beginning of the episode when Kamon is screaming (after witnessing Naota accidentally kissing Haruko), you will see a tiny imp holding a pitchfork deep in the back of his teeth.

When Noata swings the bat (guitar) Mamimi's head appears on the screen of the robot

This is the only episode where Canti doesn't turn red, although the Atomsk does logo appear.

When Naota is with Mamimi and Haruko comes on her vespa and tells them Canti is playing in the baseball game, look closely (or tape it and press "slow")
When Mamimi jumps up, she knees Naota in his back and his hands flail around and he ends up pulling off Mamimi's underwear.

Audio/visual unsynchronized: When Naota returns home from the baseball game, Canti is in the kitchen chopping vegetables. However, when Canti joins Haruko and Kamon at the dinner table, the chopping sound effect can still be heard.

When Naota is sleeping as Haruko drives him home, the first shot shows his head between her knees, but the next shot shows his head resting on her lap.

This is the first time we see someone other than Naota doing "Furi Kuri. Ninamori does it after Naota reveals that she cheated in the polls to get the lead role in the school play.

During the dinner conversation while Noata is complaining about the spicy food a skull pops up twice for a quick second and a halo appears over his head

During the dinner conversation, it's mentioned that Haruko ran over Ninamori with her Vespa. This is not accurate, however, because Haruko hit Naota, who was then sent flying into Ninamori.

Mamimi sees Canti through a camera and thinks he is a god from her game. There is a halo floating above his head with no string. However, when it shows Canti not in the camera view, he has a string.

When Haruko is about to crash into the Medical Mechanica factory, she is riding her vespa and black underwear is seen in plain sight. When she crashes and she is examined by the perverted cop, it shows a shadow showing there isn't any underwear.

When Haruko gets electrocuted, and you see her skeleton, you can see that she has a robotic skull.

After the credits end on the first five episodes, there is a brief shot of the Kamon's bakery with Haruko's Vespa parked next to it.

Haruko's scooter is a Vespa 180SS, and her guitar is a modified Rickenbacker 4001 bass.

Mamimi calls Naota by his real name during Haruko's speech about how she struck him with her vespa, however, it must be heard very carefully in order to tell.

In the preview for the next episode, "Fire Starter", the kitten that Mamimi saves is white, but in the actual episode the kitten is black.
