Dino-Sour was out adventuring in territory new to him that day, having left the firey dunes of Dragon's Valley with his jellysaur companion, Jello. Given, the entire forested area was a new experience, typically used to the heated environment of his beloved valley or of the desert he frequently visited to bother his friends, so he allowed Jello to lead him around. After all, jellysaurs had a better sense of smell and of direction than a "feral" Cookie might, and he trusted his friend not to get them lost. Dino-Sour stopped to set up a little campfire after a while of aimless wandering, letting Jello do whatever he so wished, which happened to be poking around bushes and sniffing at plants new to him. With a sniff of the air, the jellysaur walked closer to the tree Poison Mushroom was behind, having caught their scent and deciding that the curiously new smell was worth investigating, walking right up to him to get a better sniff.
