Emerald's Song of Frog

You sing a magic ballad at a sentient target you can see within 15 feet. The target must succeed at a wisdom saving throw. If it fails, the target believes that it is a frog for 1 minute. While the target is in this state, it cannot do anything but jump and move, its movement is 10 feet, and it has disadvantage on intelligence saving throws, but advantage on dexterity saving throws. On each of its turns, the target must make a wisdom saving throw to realize that it is, in fact, not a frog. Targets that cannot hear are unaffected.

It's not easy being green.
