These are so much awesome. I especially enjoyed the toenail one (did Chopper get hooves painted? XD)

Smutty ideas. How about....

Chopper only realises it's not the real Robin when.......NO! NO! NOOOOOOOOOOOOOOOOOOOOO!

I'm just gonna throw some ideas out here for smut:

Namisopp, something to do with boobs,
Robin rewarding Chopper for saving her (even if it isn't her he savd. Thought that counts.)
Zoro shuts Perona up using sex,
Bonney's fun sexy time in Impel Down! OR. What If. Robin did end up in ID (and in the care of Domino/Sadi-Chan. Fufufufu.)
DoflamingoxCrocodile
RoCho vs HogCindry: My sexy assistant is WAY better than YOURS fight. XD
NamixOldies?

I fail at ideas XD
