Entering a Morph Bubble causes Yoshi and Birdo to be transformed into one of several different types of vehicles, each with their own unique capabilities. While in this state, Yoshi and Birdo are allowed to move around as the vehicles without the babies for a limited time before being pulled back to the Morph Bubble and being turned back to normal. If the player is able to hit a Dinosaur Block while transformed, the transformation is automatically reversed at that location.
