What is a good present to cheer up a six year old boy with a broken arm?

In a glorious start to the summer holidays, my nephew broke his right arm (badly)today. And because life is unfair, he's off to Italy for two weeks by the beach next week with his parents and brother. He has a keen sense of injustice at the best of times and his brother loves to wind him up, so not being able to go in the sea is going to drive him and the rest of his family insane.

What's the best thing I could get him to make him feel better or be of practical help? (Or actually use as he is right handed?)

A rubber dinghy and a watertight plastic bag for his arm?

That is brilliant, I had no idea such a thing even existed. Thank you!
