Every year I have my children choose a theme for their birthday. My daughter chose the Lorax with truffulla trees. At first I thought I would make the trees with Pirouette cookies, but then I couldn't get the whimsical, tall and bendy look from Dr. Sues. So instead I made the tree trunks with a wire armature covered in Sculpey (polymer) clay. The tops were made with cotton candy in various colors. All the figures were also created in Sculpey.
For party favors, we took the giant sunglasses from the dollar store and added foam eyebrows and mustaches, so that everyone could be a Lorax.
