Fourberto

Fourberto is the Fourth Dimensional counterpart of Alberto. His brother is named Quaster.

History
He met the YTR in Blooper 44 of Starman3's. He did not meet his counterpart.

Super Mario 64: The Curse of the Invincibility Frames
Here, he was trapped in Bob-omberman's Factory and was saved by Alberto and Pichi. Here he finally met Alberto, and helped him out.

Personality
Alberto's personality seems to be present, but he is much more mature and understands the perks of others more often. He seems to be very patient and intelligent, as understanding who Alberto was when he met him as well as understanding how long it would eventually take for the two to meet. He doesn't mind helping though, much like his counterpart.
