Detune-shroom

Detune-shroom is the second plant obtained in Viennese Classics in Plants vs. Zombies 2. They can only be planted on instruments and will detune them once planted. Due to the instruments in it's detuned state, zombies that can play instruments in that world are forced to retune them (which will take 9 seconds) to make them functionable again. It can only be used on Viennese Classics levels.

Strategies
Detune-shroom is ultimately vital in Viennese Classics, as not only can it stall a zombie that is going to use it, it will also prevent them from using an instrument, especially dangerous ones. It's mediocre recharge is fast enough to stop a number of instruments from being played.

Double-basses are the topmost priority to detune due to its dangerous effect it will give the Double Bass Gargantuar to. Violins and Fortepianos are also a good idea to detune aswell. However, it is not recommended to detune a clarinet, due to the fact that it only gives plants the upperhand, you will most likely lose your chance to buff your plants and nerf the zombies.

Imitating Detune-shroom is also a good idea if you want to double the speed of detuning instruments. However, it is preferred that you don't use the Instant Recharge upgrade on it, as it recharges fast enough and is a waste of Plant Food.
