Galileo

Galileo is one of the main characters in Groundling Marsh. He is Vilma's older brother and Maggie's best friend and love interest. He is performed by Gord Robertson

Galileo calls himself an explorer and is constantly exploring and mapping the marsh. He is also curious about the world beyond the marsh, where the humans live. He built Stacks out of pieces of junk that humans dumped in the marsh. In some ways, he is perhaps meant to resemble a Native American person. He is very friendly, but will sometimes lose his patience, particularly with Maggie. In the title sequence of every episode, he is seen looking through a telescope, implying that he is named after Galileo Galilei, the famous astronomer. He wears a natural-looking brown tunic and pants. He has the ability to see in the dark.

He appears in the show very often. Despite being relatively mature in terms of his personality, he shares the role of the protagonist with Maggie and, occasionally, with Crystal. Each character has been the focus of a number of episodes, so the show has more of an ensemble cast.
