Pets have been a highlight of Grow a Garden since their introduction in Update 1.04.0. They come in different sizes, possess unique traits, and improve the functioning of one's garden. Yet, the passive abilities of some Pets, such as the Butterfly, carry both advantages and disadvantages. It provides the Rainbow Mutation to fruits but sacrifices several other Mutations in return.
Here's a breakdown of the Butterfly's ability and how you can utilize it for the best in Roblox Grow a Garden.
Breakdown of Butterfly's ability in Grow a Garden

The Butterfly's passive ability — Rainbow Flutter — allows it to give the Rainbow Mutation to a fruit after every 30 minutes or less. However, it only performs its ability on fruits with more than five Mutations, following which it removes them to apply the rainbow effect.
Another issue with the Butterfly's ability is that it randomly selects fruits with more than five Mutations. Thus, it may select Disco, Voidtouched, and other valuable Mutations from a fruit and remove them in exchange for Rainbow, which has a lower value multiplier. The critter's trait seems disadvantageous, but you can use it for your benefit with a subtle trick.
The Rainbow Flutter ability ignores favorited fruits in Grow a Garden. So, purchase a Favorite Tool from the Gear Shop for 20 million Sheckles, use it on a fruit in your garden, and save it from turning Rainbow. The Butterfly will only apply the Mutation to those fruits that don't have a heart icon next to them.
The Rainbow Mutation makes the fruit continuously change color and gives it a 50x value multiplier. If your fruits have Wet, Windstruck, Clay, Chilled, Amber, Shocked, Sandy, Twisted, or any other low-value Mutations, consider making them Rainbow by using the aforementioned method.
How to get Butterfly in Grow a Garden

Players can get the Butterfly Pet from the Anti Bee Egg and the Premium Anti Bee Egg in Grow a Garden. Introduced in the Friendship Update, the premium version of the egg can be purchased for 149 Robux. Meanwhile, the Anti Bee Egg can be crafted in the Crafting/Cosmetics Stand with 1 Bee Egg and 25 Honey.
Honey can be obtained by giving fruits with the Pollinated Mutation to the Honey Merchant, whose name is Onet. The NPC spawns close to the Seed Shop every four hours before the night events.
