Magnus is a bit of a practical joker, so April's Fools is a good one for him to do. This year, his prank would be relatively good natured, and do no harm to everyone. It might be basic, but a classic one never fails! What Magnus will do is go to practice early, and hide plastic insects, such as cockroaches, tarantulas, and wasps all over the place. Lockers, bathroom mirrors, even in the toilets! Maybe add some snakes into it for some variety! So what will happen is that when someone opens their locker, for example, a plastic insect will swing out and smack them in the face for effect! Another good place to hide them is in someone's gloves or skates, especially with an extra helping of baby oil so that they are slippery and do not feel so plastic. The fact that the baby oil also makes them hard to get out just makes it an even better idea.
