Splat vs. Tree, tug-o-war

Question:
 This is why I can't play tug-o-war with Splat. Look at how his back ripples when he pulls! :eek2: Lucky for me he decided that playing tug-o-war with a tree is just as much fun as playing with me. The sounds he is making is unique to when he is playing tree-tug-o-war. One time he even gave this howling noise and a neighbor came by to make sure he wasn't dying or something. :D
