Kratts' Creatures is a half-hour children's television series that originally ran on PBS Kids during the summer of 1996. The first in a series of programs produced by the Kratt Brothers, Chris and Martin Kratt, Kratts' Creatures was made to be the first wildlife show aimed specifically towards young children. It featured the Kratt Brothers as they traveled worldwide, exploring different animals and their habitats. They received assistance from their friends Allison Baldwin (Shannon Duff) and Ttark, an animated anthropomorphic dinosaur (voiced by Ron Rubin). The show ran for five seasons on PTV from June 3, 1996, to August 9, 1996, with 50 episodes, with reruns continuing to air until June 9, 2000. Due to its popularity, the show inspired an unofficial spin-off, Zoboomafoo, created by the Kratts, which premiered on January 25, 1999.
