Step 1: Borrowing
Step 2: Muffin prep
Step 3: Setting up
Step 4: How to Play
The other team pitches a muffin to you, which you try to hit with your tray (held with two hands).
When you hit the muffin, hang onto your tray and run toward first base -- however, about 6 feet away, jump on your tray (bat) and slide into the plate (another tray). (like skim boarding without the ocean...and on a tray)
