Power Quake

Power Quake is a badge in Paper Mario. It can be found in Jade Jungle, on a small, isolated island that is reached through Sushie. If equipped by Mario, it lets him perform the Power Quake move using his hammer, an upgraded form of Quake Hammer and a weaker form of Mega Quake, for four FP. On its use, Mario slams the ground with the hammer, creating a shockwave that strongly damages all enemies on the ground or ceiling, though it is ineffective on enemies that are floating or flying.

Merluvlee's prediction

 * "I see...a Power Quake Badge. You enter the jungle from Yoshi's Village and sail to the nearby island. A spear-toting enemy awaits you beneath a red Block. You defeat him. The Badge hides in the Block." -- Merluvlee, Paper Mario
