If I knew who Mr. L was , (and why he looks like a raccoon) , I would be more interested .
Mr.L is from the game Super Paper Mario. When Luigi was warped from dimensions, he hit his head and forgot who he was. He worked as a bad guy called Mr.L for Count Bleck.

and BTW, I wonder how they did this. I don't think there is any way to hack into the N 64 to do it.
