Junji Koyama’s Vegetables

Origin
Junji Koyama is a primary school teacher in Japan who always wanted to play an instrument himself but never had the skill or money to purchase a great instrument to practice on. Creating instruments out of a variety of vegetables (including carrots, peppers, asparagus, etc.) he was happy to play any sort of much until he discovered that they would rot away on him. So he decided to upload the videos on how to make and play them and became an internet star.

Effects
The vegetables never rot, once use stops playing them they can in turn play any other instrument for a week. User becomes a vegetarian for that week. Only a downside because user if forced into the lifestyle without a choice.
