Instant Unmorph
From Prime3
An Instant Unmorph is when there is no unrolling animation when leaving morph ball mode. This is usually caused by an object or wall blocking the screen when the player is unmorphing. This makes the game think the player is on solid ground and lets them act as so. (Jumping, etc.) Not so much a technique on it's own, it is a fundamental part of several techniques such as the Bomb Space Jump.
