Harry the hermit crab isn't like ordinary hermit crabs. Harry didn't want to wear a plain old sea shell or snail shell on his back. But Harry doesn't live in any old place; he lives in Legoland, and when offered a choice, opted for a Lego shell.
Hermit crabs need to wear borrowed shells to protect their soft bellies, but Harry, who resides in the Atlantis Discovery Area at Legoland in Windsor, Berkshire, rejected all the shells offered to him. Wondering if he might prefer a shell that matched his colored block surroundings, Legoland staff made Harry his very own red, yellow, and blue Lego shell. It appears to be just another shell with a Lego coating, but for whatever reason, Harry has taken to his new home. Maybe he just has excellent taste.
