Aunt Murgatroyd is back to challenge potential problem solvers with more riddles, puzzles and problems! This time the Troublemaking Trolls are itching to rid Oshkosh of mosquitoes—and in doing so, throw the planet’s ecosystem out whack! Can you help Aunt Murgatroyd defeat the Trolls and save the planet? (Not to mention making hummingbirds and bats very happy by providing their favorite snack!)
