Más te vale, mastodonte!
The protagonist of this story has an unusual pet: a mastodon. Like all mastodons, he is enormous and fierce, and also very rebellious. Every time he asks for something, Mastodon responds “No!” But when his master screams loudly: “You better, Mastodon!” Things change and get complicated…. There’s nothing more difficult in the world than trying to domesticate a mastodon, even though it also has its rewards.
