>>43477598considering how close it is to urufuman and also that it's using rinrin's backsprite (proto cyndaquil is 364, rinrin is 365. proto-cyndaquil had a matching backsprite since 1998), i think igaruu might be an alternate name for urufuman. it even matches the theming (ice type, puns about growling)
here's another instance of rinrin and proto-cyndaquil very close to one another. honooguma also appears in teddiursa's scratchpad, although borubeaa and dainabea appear constantly alongside quilava and typhlosion.
what I'm saying is that it's an alternate design for larvitar for all you know.
