Dayzee Syrup is a recipe made in Super Paper Mario. Saffron makes this out of a Dayzee Tear. It looks like any other syrup item, but it is colored blue. When used, the attack power of Mario and his friends are doubled for 40 seconds, and it gradually regenerates HP (13 HP total). It also gives the player 1000 points. This is one of the more useful items in the game, which is why Dayzee Tears are so difficult to find
"Pure Dayzee syrup! Doubles Attack and gradually fills HP. Made from a Dayzee Tear."
