The 65-Storey Treehouse (Ukrainian language)

Andy and Terry's amazing 65-Storey Treehouse (it used to be 52 stories, but they keep expanding!) now has a pet-grooming salon, a birthday room where it's always your birthday (even when it's not), a room full of exploding eyeballs, a lollipop shop, a quicksand pit, an ant farm, a time machine. The fifth book of a treehouse adventure.
