Blue Whale

Blue Whale is one of the Grow a Garden pets players specifically seek out because its ability slots cleanly into high-yield farming builds. How you get it depends on which egg is available in the shop at that moment.

Its passive ability activates automatically whenever it's equipped — no manual input needed.

Blue Whale can be mutated via special events to amplify the base effect. If you have an unmutated one, consider holding it until a relevant event before using it for trading.

The Blue Whale is an exclusive prismatic pet. It can be obtained by redeeming a code from buying a Grow a Garden plushie from PhatMojo.
