Savio

Savio is an even sneakier Boa then Kaa (in fact, he is rumored that he's Kaa's son, but he can't mastered hynopisum) but he does have a plesent personaly that hides his villain nature, but it never fools Skipper, as his years of milatary exbertise (and persisient paranoya) helped reveled his treaheriou nature.

in Spongebob and friends meet the great mouse dectecive, he was Ratigan's pet, assuming that Ratigan and his thugs raided the transport truck heading to new jersey, and Ratigan somehow got to Amarica.

he had the plesure to sevre as an exacueioner for Ratigan's enemies, or any of his minions who called Ratigan "A rat" and Savio finds it plesureable.

Savio was defeated by the Penguins (and bert, the elephant, like before, who was tranported to London by the aliens, Monty and Seven11) and he was mentioned by Abbott mouse that he was being tranported back to amarica, and i was even shown in a clip from the ending of "The Big Squeeze" that he tried to scare the tranporter (who oddly looks and sounds like Zookeeper alice) as she states, "This isn't New Jersey tough guy"

dispite him being defeated, Savio is exsected to return along side with Deadpool and other villain leagers in Spongebob and friends meet Oliver and Company.
