Easy "Stratospheric Picnic" Achievement
A teleport staff is required to launch a pancake into the air. When you use the teleport staff, it creates a flattened block where you are currently standing. Moving your character will cause it to pop up. Time this so that a pancake is on top of the block as it pops up, which will then launch it into the air.
