He is found in the wilderness after the player's accident with Gary's invention, along with other puffles. He is the only puffle that doesn't run after you appear. After giving him an O' Berry for the first time, he'll light on fire, fly for a bit and quickly burn out, smile, and follow you. Giving him O' Berries after that will once again result in him lighting on fire, flying for a bit and burning out. You can use this ability of him to light the wood in the cave to make a bonfire. At the end of the mission, after sleeping, he will have disappeared.
He is found in the wilderness near a treestump, after you follow Klutzy there. He'll be hungry because the O' Berries of the bush were taken off and put on a bag, which is attached to a tree using a rope. After discovering how to get the bag, you can give him an O' Berry and he'll follow you around. He is small enough to fit through the pet door in the cave, so if you throw an O' Berry there, he will enter the pet door and open the big door for you from inside. After you get trapped, you can throw O' Berries at places in the mechanism inside the cave. He'll get in this places to eat the O' Berry, therefore helping you. After finding out how to get out, if you open the door, snow will fall down in the door's entrance. Grabbing hot sauce, putting in on an O' Berry and feeding it to him will result in him lighting up on fire and bursting through the snow, opening an entrance. He'll fly in the sky and you don't see him again until the end of the mission, where you can see him still flying in the sky.
