"Full-Of-Wonder, Wonderful Day" is a song from "Snuffy's Thanksgiving". It's sung by Jay Jay and Snuffy as they fly through the air on their way to town, expressing their excitement about Thanksgiving and what they do on this special day. The song is reprised by the cast at the end of the episode at the Thanksgiving dinner, shortly after Big Jake's return and Snuffy realizes the true meaning of giving thanks.
