As we were exploring, we kept finding this grayish casing everywhere. Arianne explained that it was the discarded egg capsule of the Moon Snail! So there had to be an actual Moon Snail around here somewhere...and she found one!

This is another large creature that likes to burrow into the ground. As you can see, he's too big to even fit in his shell! And look at him try to run away, dripping down from Arianne's hand! Tee hee!
