¿La caca de quién?

One day, Papa Mouse announces to his mouse children that he's going to take them to the zoo, but only if they're good, which means there's no poop! However, before leaving home, the two brothers can't help but wonder... What will the astronauts' poop be like? Shiny silver poops from the space age! Weightless poops that carry a rocket and spin like planets! Chefs, balloon sellers, blue whales... they must have a unique poo, and the little mice imagine what each one of them will be like. Once they get to the zoo, things escalate, because of course each and every animal in the zoo has to do a special kind of poop! Finally, Papa Mouse is forced to explain the whole truth about poop to his curious children. And just when he thinks they've got it, a funny (and smelly) surprise will make rats and humans laugh out loud.
