Sun booster zombie

A zombie that causes sun making plants to speed up, to the point so much sun is created from it that the value of sun decreases and the cost of plants goes up at a greater rate, some can even go over the 9990 limit, so you have to kill the zombie, and wait for the sun production to slowly go back to normal and the prices will fix themselves.

If it stays long enough it will speed up sun producing plants even more causing prices to sky-rocket even faster as sun becomes less valuable and it takes longer to fix itself.
