Story:
Zazz heard stories of Pampaku from Mercury and decided to this critter out thinking he can't be stronger than Pampama and might reverse his diaper arm if he can defeat him. Zazz figured a sneak attack could work, so Zen disguised himself as a diaper to distract Pampaku (not a good idea). Pampaku seeing a lone fox diaper decided to help himself and went straight to eating the fox pamp. Zazz found an opening used both Crush Claw and Gel Slash on Pampakus back, but got stuck also and since Zazz used a diaper attack, it made Pampaku slightly stronger, Zazz did his best to get free, but found himself sinking into Pampakus body. Zazz found it highly discomforting as Pampaku back was pulling him into his body and was soon completely absorbed by Pampaku, the big critter looked down at his belly and mocked the new faces added to his bulk.
End

Interlude:
Pampaku could fix Zazz's diaper arm if he wanted to, but it has Pampama's scent on it and Pampaku doesn't want to touch other critters' diaper work all so as zazzy not happy about what happen Zen is all ways happy to be a diaper in any way even being a part of Pampaku.
