Menu transition

When entering a checkpoint or when exiting to the Menu, there is a transition that zooms in to the right, entering a checkpoint. (It's the opposite for exiting to the Menu.) It also happens when you run out of balls, as you can't continue with gameplay. If you have an Infinite Balls power-up in your inventory, if you're quick and activate it, you can continue with gameplay for a few seconds, therefore preventing the transition.

The three-dimensional layout of the checkpoint on the menu, as well as its depicted in-game makeup, is shown, often as a surface mesh only. Textured surfaces also glitch out and mess up the perspective, and thin multilayered walls also separate, as do other pieces of debris and even entire objects.
