M2, T7: The kids visit the Big Pond to attend the Biome Block Party. While attempting to win the leaf-necklace contest, Keenan Chirostemotes claims the Pteranodon sibs can’t compete for the prize for “dinosaur” with the most leaves because they are not dinosaurs. This launches the kids into a song called “That’s Not a Dinosaur”, as all the non-dinosaurs sing their piece. In the end, the game rules are changed to include all creatures, even non-dinosaurs, in all the contests! The Nature Trackers go on a visit to the Big Pond, where Tiny hopes to see her favorite flowers. The Conductor tells her that if the kids gather seeds at the pond, they can bring them home and plant a garden full of those same flowers at the family nest! The kids all get into it, gathering seeds and bringing them home, where they plant a garden, and meet its new inhabitants, including Sammy, a friendly slug, who explains that slugs, spiders, and butterflies all help to make a garden complete.
