Design and animation for:
1. tiger (same animations as lion, only different design)
2. elephant (walk, run)
3. hypo (walk, run, open mouth)
4. one bird (similar animation with bird you did already)
5. lion roar (same lion you did) and tiger roar (same as lion)
So for tiger you can copy all animation moves of lion.
Only design of head and coloring is a bit different.
I will provide example designs.
