Elemental tablets

The Elemental Pills were three pills in Super Paper Mario. There was one for each element (apart from Air.) Mario, Peach and Bowser found out how to get them after lookeing at the Cragvision sets throughout 5-2, the Gap of Crag.

Stone Pill
Mario had to run in circles around a statue of Yoshi to get the first Pill. It had a picture of a rock on it.

Fire Pill
He then had to light a fire with Bowser under a stone archway. The second Pill had a fire on it.

Water Pill
Mario had to dive to the bottom of a river to get the third Pill, which had a water droplet on it.

Cudge
He then climbed a massive stone pillar and hit an Invisible Block. He climbed up the ladder extending from the block to reach three small pillars. He put the Pills in and who should pop out but Cudge, the Hammer Pixl. Cudge smashed the yellow block and Mario and friends procceded to Floro Caverns.
