I'm not fully versed with the beast wars toys since I'm not the least interested in most of them but here you go:beast wars toys.
iguanus = kitbash into a seal (minimal level repaint and retool of head)
grizzly or other repaints - white one as is.
airazor = kitbash into a goose (hard level, head and long neck has to fit in bot mode)
snarl = kitbash into a beaver (retool of head
big horn - as is.
long neck or ramulus = kitbash into a moose (hard level)
combining would be hard but that's the fun part.
unless you guys go the easy way like that dinobot wannabe combiner I saw sometime ago.
this one on the other hand would be nice.
