"Flotter and the Tree Monster" was one of the stories of the The Adventures of Flotter holoprograms.
While participating in this story, Naomi Wildman persuaded Flotter to be friends with Trevis after learning that Trevis was not a monster and that Flotter and Trevis both needed each other: Flotter's water helped Trevis' trees to grow and Trevis's trees shaded Flotter's water from the sun.
