S1·E52 White-Nosed Bats

Rosie, Mandy, and B.B. try to help a horse escape constant agonizing bites from several mosquitoes. Coming to the conclusion that there are too many insects due to there being no bats around to eat them, Rosie refuses to look for them, being severely afraid of bats. Things get complicated when they find out the bats have white nose disease, and Rosie is refusing to touch them.
