Biography
Sigmund Smith was in the episode "Evil Mascot". He built a weaponized version of Riptide State's mascot, Sigmund the Seagull, and used it to attack the sports team captains of Malibu University. He wanted to ensure that Riptide State won the annual Beach Sport Mega Tournament after Malibu University had won it 6 years in a row.
His plan was foiled by Samantha, Clover, and Alexandra, who allowed Jerry Lewis to take his kitten to WOOAP (World Organization Of Animal Protection).
