In A House for Hermit Crab by Eric Carle, the hermit crab has outgrown his shell. He finds another, bigger shell but thinks it is very plain. As hermit crab travels around, he looks for ways to decorate his shell. He ends up with many friends this way including a starfish, a snail, a sea anemone, a coral, a sea urchin, and a lanternfish. Hermit crab is happy with his home, but one day he outgrows that shell too and must say goodbye. This vibrantly illustrated book is perfect for helping young readers learn to deal with change and say goodbye while teaching them about fun and fascinating sea creatures.
