Episode Description:
When Spike runs out of gems to use for a cake, he comes up with a scheme of pet-sitting for Twilight and her friends while they are off to the Crystal Empire in exchange for gems. Unfortunately, Spike finds the task daunting than he expected and has no time to mix the gems into his cake in which ends up spending his gems as an attempt to restrain the pets. When he along with the pets and the Cutie Mark Crusaders accidentally board the Friendship Express to the Crystal Empire, Spike fears being exposed as a fraud when he admits to the pets that he put himself over their needs. The pets then cooperate and stay quiet until the Express returns to Ponyville where Spike happily returns the pets to their owners. However, he absentmindedly eats the last gem before using it for his cake.
