Slime Rancher

To earn this achievement you need to purchase 10 DIFFERENT slime toys. In order to purchase slime toys, you need to be a Rolling Beetle I (level 8) in the 7Zee Rewards club. After you are a Rolling beetle I you will receive an email saying the slime toy machine has been built on the ranch. Interacting with the machine will allow you to buy 8 slime toys. In order for you to be able to get 10 slime toys you need to be a Rolling beetle III (level 10). This will unlock Advanced slime toys, adding 3 different toys. Assuming you have already purchased the starting 8 toys, you just need to buy 2 of the 3 new toys and the achievement should pop!
