She is 78 years old, and was born in April 25, 1935.On the first episode she appeared on she didn't have a mustache until Sonic pulled Doctor Robotnik's mustache off and stuck it on her.

When Sonic invades her lair, she tells him that if he doesn't cooperate, she will destroy Youtube Poop with a Subspace bomb. Sonic reluctantly agrees, and is locked in a prison cell.
