Mega Jump

Mega Jump is a badge in Paper Mario. It is at the end of a road near the icy stairs on Shiver Mountain. When equipped, it allows Mario to do a Mega Jump, a one-hit jump attack that costs six FP. The move acts similarly to a standard jump, but deals more points of damage than one if timed correctly. There is an unused badge in the coding of Paper Mario: The Thousand-Year Door that resembles and behaves like the Mega Jump badge.

Merluvlee's prediction in Paper Mario

 * "I see...a Mega Jump Badge. You are ascending a frozen mountainside, climbing icy stairs to the Crystal Palace. At a flat platform, you continue forward and find a red Block floating in air. You smash it and the Badge becomes yours."
