Gelatin Salad

Gelatin Salad is an item that appears in Galactic Hot Dogs Island.

Role in Galactic Hot Dogs Island
Once you obtain the Gelatin Salad (see below), you want to equip it and go to Princess Dagger's Planet.

While it is equipped, go stand under a falling rock. The rock will bounce up and down as long as it's still bouncing on the gelatin.

Use the Gelatin Salad to break the rocks so you can get to Princess Dagger.

How To Get It
Go to Cosmoe's planet and get the Seed Pod. Go back to FunkyTown and give it to Boba Fleigh (the blue bear). He will turn it into Gelatin Salad for you.
