Captain Planet and the Planeteers (1990)

S4E16 Going Bats, Man

A wave of fear sweeps through a small town as news spreads about a swarm of killer bats on the loose. In a state of panic, the townsfolk decide to exterminate an entire colony, blaming them for the supposed attacks. It falls to the Planeteers, along with a local bat specialist, to step in and demonstrate that these misunderstood animals are far from the vicious monsters they're believed to be.
