Lufba looks like a neat project. Be fairly easy to use a POTF2 Joh Yowza (packed in w/ Sy Snootles) as the base - looks like the only real difference is maybe some coloration. The trick will be pulling off the rifle. I thought I had a Yowza, but I misremembered - it was a Droopy McCool. Otherwise, I've give this a go in a heartbeat.
Snoova was already done - weeeeell, Chewy disguised as Snoova was already done by Hasbro. Not satisfied by that version? (just picking
)
