Olaf, the rootfit master
Olaf is all about sports. His body was made for it, and he excels in everything he sets his feet on. He is the fastest runner, the highest jumper, the most precise thrower. It takes quite some nerves and character to compete with him because he wins every time. Not that he tries to so much, he was just born that way.
He is the happy soul of the forest. With a wide smile and an encouraging word for everybody he makes every day a bit brighter. He loves to spend time with Lala, because she appreciates his good spirit and because he also loves fashion. They make a good team, and for Olaf, team spirit wins.
Even though he excels in all disciplines, what he loves the most is rootfit. It's a cross-fit exercise where you run through the forest as fast as you can, without touching or stepping on the tree roots. Rootfit is actually his invention, and he teaches it to the next young generation of the magic forest inhabitants, to create a collective rootfit movement. Maybe they'll even go the Olympics.
