The Revenge of Flying Chibita-zansu!

Chibita gets into R/C model planes after seeing the sextuplets' new expensive toy bomber. However, he's barred from the model shop and has to pay Osomatsu to play with theirs. After an accident causes the sextuplets' R/C to break, the kids chuck it out, leading Iyami to repurpose it into a new way for Chibita to get his revenge.
