Squishy Rex needs a Rex!

Hey guys, I need to ask a favour of anyone who can help. Basically I need a Custom Rex Boss that replaces the SMB3 Bowser.

I would like to have it look like my Avatar, so here's a link to the image.

The fireballs will be replaced by SMW Yoshi Fireballs (If Possible) and the codes the same as SMB3 Bowser. Unfortunately there is only my avatar image to make it from so its gonna need some imagination. I would do it myself but I really struggle making npcs, yet I can make everything else! If you want take up the "challenge" then just PM me. Plus more than one person can take it on to make different customs to trial and I will use the best in my episode as the Secret Boss. You will be credited and I will help with anything that you need (unless its an npc except if its only a recolour), BGs, BGOs etc.

If anyone can help it will be much appreciated. :-D
Thanks, Squishy Rex.

might be able to make ill let you know in about 1 or 2 days

Thanks for that, it is really appreciated! :-D :-D :-D
