Max and Ruby's Christmas Tree

s. 3, ép. 138: It’s time to trim the Christmas tree, and Ruby wants to decorate it with all her favourite ornaments, so the tree will look 'Beautiful.' Max thinks his snakes and bugs and other toys are 'Beautiful'. In the end, when Ruby discovers they forgot to put the star tree topper on the tree, Max uses one of his toys to put his pin-wheel on top. And they both pronounce it 'Beautiful!'
