Mallowolf are first seen and level 31 and will vist your garden at level 32. Here are a few things you will need to do.
1. Make sure you don't have a Captian Cutless in your garden because it keeps the Ruffins away.
2. It will need it to eat a Pixie. A Pixie is the Swanana and the Rashberry cross-romance.
3. Once it has come to the "lightside", is now your pet you can have it scare the next Ruffin that comes into your garden.
