 * Both Sans and Flowey can modify the Bullet Board in an irrelevant size. Flowey to a tight space and Sans which extends entirely into the sides of the screen. Sans also need to teleport to keep pace.

Papyrus also extends bullet board in height to dodge the giant bone...
 * Again, both can modify the game over screen.

Muffet can do that too...
