"I saw it from the boat ride the last time. The swamp goes all the way in a circle around this hill, but that goes into it. I saw light through the other end, so I think it goes to another part of the swamp, maybe where the big dragonflies nest at." And Mistral rings his bell then. He wouldn't have done this last time, with the water poisonous, but with it safe now he feels it's ok to summon Sealion.

Sealion is tall enough for them to climb on to reach the tunnel entrance, if the Magelets can be coaxed into doing so. They're still a little skittish around the giant ice monster.
