Jammin' Jelly

Jammin' Jellies are one of the greatest general FP-healing items in the Paper Mario series (second to Jelly Candy). The item can restore fifty FP. Their name is a play on "jam and jelly."

Jammin' Jelly is the FP-restoring counterpart to the Ultra Shroom, and the two put together make the Jelly Ultra, which is able to recover fifty HP and fifty FP. This item can also be cooked by mixing an Ultra Shroom and a Point Swap in Paper Mario: The Thousand-Year Door.
