I have been unable to find the exact author and file this came from. If you know who made this original model, please let me know. I am pretty sure the animations were made by Master Luke, but I'm not so sure about the model.
Hidden/Spoiler:
I will also upload the original model because I can not find any links on GT or MODDB to this asset.

EDIT:
The animations were indeed made by Luke, so be sure to credit him! I am still on the lookout for the creator of the model, however.
