Tales from the Cryptkeeper (1993)

S1E2 Nature

At a family picnic, brothers Rick and Teddy begin to harass an ant mound, but their fun takes a wild turn when an anti-magnifying ray shrinks them down to the size of ants. Now tiny, they quickly form an alliance with the ants to navigate various challenges together. The biggest threat they face, however, is their baby sister, who now looms over them like a giant.
