Blue Beach Koopa Troopas launch themselves off slopes to ostensibly demonstrate momentum physics. However, the physics are actually faked, and instead of using actual momentum, the Koopas are simply programmed to jump whenever they reach an upward slope. This only happens to Blue Koopas who spawn into the level without a shell, and those knocked out of their shells will operate as normal when approaching similar slope configurations. While these Koopas appear shell-less in a handful of courses, only Cookie Mountain and Groovy include ramps they can jump from.
