1980's - 1992

Baloo's neck becomes shorter and his fur becomes a bit shaggier. He also no longer has a view screen under his neck for the performer to see through out of.
Baloo HKDL 1991 - present Baloo's eyes are snake-like, his nose is brown and the claws on his paws change into normal fingers. Also, his muzzle is flesh instead of gray unlike the one in the actual franchise. But another variant did have a gray muzzle and his nose was black again, but it lasted from 1991-1992.

This design was also used for the polar bears for the 2015 edition of the extinct Magic Kingdom castle show, Celebrate the Season.
