I will give 15 no 20 प्रॉप्स to whoever can figure out how the mutagen works BEFORE IT IS REVEALED IN THE SHOW!

The Mutagen Effects the Victim in a way that causes them to resemble the last creature they saw before the mutation; या a creature they know they had contact with often या recently. for instance the last creature Baxter Stockman AKA Buzz Kill Saw Before his Mutation was a fly. His Bug like form was the result of the Mutation process.

The Kraang never perfected the Mutagen. They needed April to perfect it. Yes it will have an affect on anyone who touches something after being hit द्वारा it and that person/victim will turn into that. The only way to cure it या de mutate that person is with Retromutagen.
