Lol im guessing you need the Special Medicine, right? You can find one in the game. I found three. Its not hard to find them, Here's a location for One.
Fossil Beach Zone!
Item in Treasure Chest - Special Medicine x 1
Go inside the Dino Fossil's Skull, go to the back of its left jaw , you can jump up to get to this Treasure Chest
Silver Mountains!
Item in Treasure Chest - Special Medicine x 1
Location / Direction: - Outside the cave where the second boss is. Without entering the cave, look to your left to find an ice rock 2 platforms above you. You need to find a mushroom to get to the first platform, then look for a second mushroom to get on top. The Treasure Chest is within an ice block, smash the ice block using your Pick Axe to get to it.
There's two.
