Buzz Lightyear of Star Command (2000)

Season 1: Episode 49

Zurg nabs an exhibit of an extinct species of large, Alien (as per the movies)-esque insects, planning to resurrect the species in order to help him in (...what else...) take over the galaxy. Dr. Ozma Furbanna is roped into helping Zurg revive Alien-style bugs, by having her scientific morals preyed upon. Zurg sics the bugs on Capital Planet. Before things can get too out of hand, Team Lightyear discovers that the bugs can be stopped by belly-tickling (...it over-rides their nervous system...), and with that they manage to save the day.
