Nightshade bush
This little bush is dark and mysterious. It's recommended that you keep well away from its berries, because they are poisonous. If you know what you're doing, the nightshade bush can make a pretty addition to your garden.

A Nightshade bush is a bush that produces Nightshade berries which are poisonous fruit. When a Piñata eats one it will become sick. Making a Lickatoad eat one then tapping it with the shovel right after will turn it into a Lackatoad.

Though, if you use the Birdproof Fence, you will be able to keep piñatas you don't want to get sick, or evolve, away from the bush. Including flying piñatas. This will make sure you don't have to spend all your money on the doctor.

Fertilization

The nightshade bush needs to be fertilized once when the first set of growth buds appears, then again when the second appears, and finally when the third set of growth buds appears.
