Antigone told Sour he could decorate the Christmas since Plume was decorating the rest of the house. Antigone should have foreseen there would be problems with the shortest wyrm of the squirm to decorate a tree.

Luckily, Halie is there to remind 'Tigone that she did give permission to decorate it however he liked as long as it was Christmas-y.
