Step 1: Find a good, robust sleeping pig. His belly should be round enough to slide off of.
Step 2: Jump from the ground onto the pig.
Step 3: Jump from the pig onto the ground.
Step 4: Jump from one side of the pig to the other side of the pig.
Step 5: Fall off the pig. He's a pig. He doesn't care if you fall. Just be careful.
Step 6: Jump all over that nasty pig. Right on top of him. He won't even notice you're there. Just go to town.
Step 7: Gently dismount from the pig and go about your otherwise wonderful life as an excited baby goat.
Great work. Don't forget to congratulate yourself on a pig-jumping job well done.
