Godzilla: The Series
The Twister (2x11)
:
During a nice relaxing day at the beach, the team is caught off-guard by a twister. They trace its origins to an experimental energy experiment at a local power plant, as well as discovering strange tracks near the plant. When the twister strikes again, H.E.A.T. discover that a giant mutant shrew has been bonded to the twister, creating a "Shrewster", and now the race is on to defeat it before its ravenous metabolism drives it to eat everything in New York.
