If you want to create a truly impressive seaside fairy garden setting, you need to make sure that you have all of the right décor and terrain pieces to make it look like a lived in, fun place. This means you will need some fun little critters that can be friends with your fairy, such as this Blue Shell Hermit Crab. He’s a cute little red fella with a big smile on his face. He’s carrying his blue and green shell home along with him.
