To un-grump Mr. Grumpus, everyone decides to cheer him up with a gift and tree decorations. Wubbzy shows it to Mr. Grumpus, but instead of smiling, Old Man Grumpus gets raging mad, and chases everyone away and takes down the tree decorations before noticing the big present under the tree. He was almost afraid to open it, because he was expecting to find long underwear, just like every year. But instead, when he opens it, he finds the gift he's always wanted for all those years, a real working choo-choo train. After the true act of kindness the Wuzzleburg folks did for him, Grumpus feels mighty bad for how he treated Wubbzy and the others. But then, he came up with an idea of how he could make things right again.
