That page means to show Pekka starting to teach Myces about the world outside what she already shows. It's implied he'll be doing that all winter, and the next ones if he can.
That page also has fashion pictures. Leggings, such class!
(I googled for "Sunmart". There's a small chain of groceries stores by that name in the USA but for clothes stores it seems to be free.)
Oh god, the Troll in leggings was hysterical!!!
Well, with what we've seen of trolls so far, leggings are something they would wear!
