I'm Not your... puppy?

And I have actually animated about 4 other signatures, but according to reviews from friends, my current one is proving rather hard to trump. Do you have any suggestions as to a storyline or setting?

Alas no. It just feels "time" for an updated one, but it is rather hard to think of a true improvement.

Finding one of the people who insist on doing smegas with the most butchered and idiot gibberish and beating them senseless with their own smega would probably be one of my personal fantasies, but it's still not quite on the same caliber or topic as yours.

You could do a boss stealing scenario - One of those many people who tries to either "claim" a big foot for example as theirs (Without being able to even hit it) or one of those people who insists on trying to steal them (or Anego) from people who can hit them but can't withstand having the boss shoved on top of them.
