These rabbits were in fact on a raft, as were assorted rats and owls. There may have even been a reindeer.
On a raft. And a boy was sitting on the raft.
The picture worried me, I must say. There was an otter swimming in front of the raft, and I used to lie awake worrying about this otter, having to pull the raft, with all these other wretched animals on it who shouldn't even be on a raft, and the otter had such a thin tail to pull it with I thought. It worried me.
Then one day-- and remember I had been looking at this picture every night for years-- I suddenly noticed the raft had a sail. Never seen it before. The otter was fine, just swimming along.
