SpongeBob SquarePants Underpants Slam!

This is a cumulative achievement. Your special meter is the meter right above your name in the top left corner between the star and the underpants counter.

In order to fill this bar simply kill jellyfish, break objects by hitting the jump button (default A) and while your'e in the air pressing hte jump button again. This will cause you're character to do a ground slam. It doesn't necessariy have to be right under you as there is a small impact radius. Also the floating bubbles with the dark blue D-Pad/cross looking icons will add to your meter.

Once your meter is filled hit the special button (default X). Rinse and repeat 25x.

This achievement is cumulative and can be done over the course of several games.

Another easy Achievement from Spongebob...

Just keep playing as normal, but every time your super meter fills up, press Y to use your super power. After 25 times you will unlock this Achievement.

Super Moves are moves you can use after you fill up your power meter on the northwest corner of the screen. You fill up your meter when you break crates, barrels, and chests and kill jellyfish. To use this move, you have to press the button. Rinse and repeat this 24 more times then achievement pops.
