El paraguas verde

"Elephant is enjoying a peaceful walk with his green umbrella, when suddenly a Hedgehog says: I believe you have my boat. Elephant listens patiently as Hedgehog insists: I crossed deep oceans . . . tasted the salty spray of whales [in that umbrella-boat]. Cat, Bear, and Rabbit soon interrupt Elephant--each claiming that his umbrella is really their tent, flying machine, and cane. Elephant is flabbergasted--after all, it's an umbrella, and it certainly hasn't been on any adventures more exciting than a walk in the rain. Or has it?"--Publisher's description.
