Grumblump

Grumblumps are large, multicolored crystal blocks that appear in Super Mario 3D World in the level Grumblump Inferno. They have a smiling face on each side — which strongly resembles that of a Rhomp from Super Mario Galaxy 2 — and behave similar to Tox Boxes. They can be either cubed or rectangular in shape. Once the player steps on a Grumblump, the smiling faces turn into frowning faces, and it starts gradually moving along a set path through the lava in the level, turning over on one of its sides at a time (Grumblumps act as the only means of traversing these parts of the level). As it moves, the player must move with it to stay on top of the side currently facing upward and avoid falling into the lava until it reaches the end of its path. A Grumblump may also encounter a slope along the way, at which point it will slide down on the side currently facing downward. If the player Ground Pounds a Grumblump, the faces will turn angry, and it will move faster for a short period of time. Occasionally, two Skipsqueaks appear on either side of the player to serve as guides for timing running and jumping movements when trying to stay on top of the Grumblump. Template:BoxTop
