Point Swap
From the Super Mario Wiki
A Point Swap.
Point Swaps are items found in Paper Mario: The Thousand-Year Door at the Glitzville Shop for five coins. This item will switch the player's HP and FP, not exceeding max. The Point Swap is very much like the Swap Card.
[edit] Cooking
Cooking an item with Point Swap often gives the reverse counterpart.
(Ultra Shroom + Point Swap = Jammin Jelly)
