Big thanks to ShinKitsune.

(I can't find the page for the Yoshi and Koopa ones, but the Sketch showed you're not missing much.)

The Roo and Gaomon (Shins recent form) find Pampaku funny (Never laugh at him). Instead fighting he summons his diaper minions to do some work. Both try their hardest to fight, but fail as the diapers wrap around and absorb them. Pampaku enjoys eating either diapers or diapercritters, When he used his jutsu again, boy is he confused (Which is rare).
I'll leave it up to you all about his reaction.
He's either confused how so many faces got on his diaper, or he's wondering why all the Shins are happy.
He's used to either Shock, Terror, Anger, Confusion, Sadness, or Neutral, yet they're all happy. Guess his jutsu evolved.

Pampaku belongs to Me.
Shins characters belong to him.
