Sonic Werehog on Feet in Sonic Unleashed (PS2)? Impossible.

You cannot make the Werehog run bipedally in the PS2/Wii version of Sonic Unleashed.

Separate Codebase: PS2/Wii version built by Dimps (not Sonic Team). Different engine (Hedgehog Engine not used).
Werehog Gameplay Redesigned: Dimps made Werehog exclusively quadrupedal (knuckle-walk) for:
- Simplified animation rig (no biped/quadruped blend).
- Lower memory/CPU budget (PS2 32 MB RAM, Wii 88 MB).
- Combat focus: Arena brawler on flat planes, not 3D platforming.
No Hidden Toggle: No debug menu, cheat, or unlock switches locomotion. The skeleton/animations don't exist.
