Aaahh!!! Real Monsters (1994)

S3E11 Eye Full of Wander

Ickis, Krumm, and Oblina decide to have some fun in the sewer, playing catch with one of Krumm's eyes. However, the eye slips from their grasp and plunges into the water, only to be gobbled up by a boa constrictor. This sets off a chaotic pursuit as the snake slithers away, leading the friends on an unexpected adventure. Their wild chase culminates at a rock concert, where they finally manage to catch the snake and retrieve Krumm's eye.
