Mushlers to the Rescue

Having rescued a Mushlet, Mush-Mush, Chep and Lilit become heroes in Mushton, and they're loving it! So Mushlers create a rescue team but alas, no one needs saving! How can you be a hero when there is nothing to be heroic about? Then when some Mushlets become adrift on the river, Team Mush-Mush, with Morel's help, have to save the day again.
