What does Baby Panther say? He says "Diego! Diego! Meow! Meow!" and then he jumps into Diego's arms to welcome him with a warm cuddle.
Baby Panther is the animal that Diego is closest to from all his adventures in the rainforest and they are companions throughout many of the episodes.
Baby Panther is still so youthful and bouncy and eager! But sometimes his enthusiasm gets him into sticky situations that Diego has to help him out of. But he also has incredible physical skill and is a keen adventurer, just like Diego.
