Wallop

Wallops are enemies that appear in Super Mario 3D Land. They look like Whomps, except they are shaped like a fort wall. Instead of attempting to squash the player by slamming on the ground when they get too close, Wallops block their way by following their movements. Wallops can also jump whenever Mario or Luigi jumps and then slam the ground. After a Wallop jumps, there will be a few seconds in which it will recover, giving Mario or Luigi a chance to pass by it. When the player is a certain distance away from or behind a Wallop, they will be in a state of dormancy, in which their pupils are not lit and their feet have retreated into their bodies, until the player is in front of them. Mario or Luigi can destroy Wallops by turning into a statue above them or below them when they jump. They make their first appearance in World 3-1; they also appear in World 6-4, World 8-6, Special 3-5, Special 6-1, Special 8-4, and Special 8-Crown.

Trivia

 * Like Whomps, Wallops seem to be inspired by the Japanese mythological creature . Nurikabe block the path of travelers, just as Wallops do.
 * The name Wallop comes from "wall", due to how Wallops look and behave like walls all the time, and the term "wallop", which means "to make a loud crushing noise" or "a large attack or beating".
 * By running into a direction and immediately turning the other way, Mario or Luigi can get past a Wallop without jumping.
 * A Wallop's smile resembles the one used by Rhomp and later Grumblump.
 * Wallops bear a striking resemblance to Blocky from the Kirby series.
