This is what happens when Izzy plays too much Viva Pinata, andThe World Ends With You in a close proximity.
I have reasons for who is who though.

Neku is a Pretztail, firstly because I was like "FFFFFFFFFF ORANGE HAIR/FUR!", secondly because I wanted most of them to be fairly 'normal'/low-level pinatas. He was one of the funnest to draw, and not too difficult to colour.

Shiki is a Kittyfloss, but was orginally going to be a Swanana, because they care about their appearence, but then after having one of the 'Bastard-Birds' hanging around my garden, I decided on a Kittyfloss....mainly because of Mr. Mew. She was not easy to draw, but not hard either, kinda in the middle. Colouring was also not easy, but not really hard either.

Joshua is a Chewnicorn, which proudly holds the title of GAYEST PINATA EVER CREATED. He's a higher level/rarer pinata due to his *SPOILER* status as Composer *END SPOILER*, plus he gives off a rather 'effminate' vibe. He was begger to colour though, but the other one which was most fun to draw. I'm glad I didn't draw him as a Dragonache.

Beat is a Buzzenge, and Rhyme is a Sparrowmint. Rhyme was originally going to be Candary, but that would mean that she was eligiable to be eaten by Beat So instead she became a Sparrowmint.
These two were both the biggest pains in the arse to colour and draw. Toward the end of Beat, I was like "Oh stuff it!", and didn't bother to follow the Sparrowmint pattern, when I coloured Rhyme, just randomely dabbing brown here and there on her.
And just in case it's hard to make out, Rhyme is on Beat's back.

Sorry about the shoddy logo, I couldn't really do much about it. :
