No Chocolate Rolls for Shishimaru (Shishimaru's obsession of chocolate rolls) (チクワなんか嫌いじゃわんの巻) is episode 352 of the Ninja Hattori-kun 1981 anime.
After Shishimaru becomes addicted to chocolate rolls, Hattori crosses out a picture of chocolate rolls and bans Shishimaru from eating them for a week. However, when Shishimaru and Shinzo are lured around by Kemumaki and Kenichi, Hattori uses his ninja techniques to try and stop him. Shishimaru pretends to dislike chocolate rolls after that, before revealing his true feelings...
One day, when Kenichi is doing his homework, Shishimaru comes in and tries to eat everything in the room (and ultimately swallows a pencil), much to Kenichi's annoyance. Hattori comes in and tells Shishimaru to cut out the chikuwa from his diet - at least for a week.Shishimaru goes to the park to mourn the loss of his beloved confectionery, but has an idea when a joyful Kagechiyo comes along with a coin. Shishimaru swallows the coin, but spits it out when Shinzo orders him to do so. Later on, after Kagechiyo gets his money back, he calls Kemumaki and tells him to come. He brings a six pack of chikuwa and a slice of cake (which Shinzo is cutting down on), and tempts the two of them to eat. Shinzo resists his temptation, but Shishimaru tries to guzzle the lot and is stunned after the chikuwa are revealed to be firecrackers. Shinzo is amused. Later on, Kenichi tempts the dog with rolls, saying that they aren't fake. Shishimaru tries to guzzle them up - but is stopped by Hattori just in time. They then go and dress a bakery up in chikuwa coverings - and when Shishimaru tries to eat them, the owner comes along and shoos him off. The gang then disguise a lamppost, but Shishimaru catches a glimpse of them and they are finally exposed when they dress up as a collection of chikuwa in the garden and are soaked with a hosepipe.
Drying off, Kenichi grumbles that Shishimaru ruined their plans. As Shishimaru comes in pretending to have chikuwa, the gang rejoice - but happiness is turned to irony when Shishimaru eats sixty-two chikuwa on a plate!
