The Trophallaxis is an Item that can be found within common locations, including choice enemy Camps, given by Spouses, and rarely as a reward from Seasonal Festivals. Upon being picked up, all Bees and Hummingbirds will water all Crops they pollinate. The effect is instantaneous, meaning that whatever Crops the mentioned Farm Animals will pollinate will be watered without a watering animation. Note that because of how Bees and Hummingbirds do not pollinate Fruit Trees they will not benefit from Trophallaxis.
Compared to other means of watering, Trophallaxis has the benefit of not possessing a watering animation, providing it's instant effect. In that regard it can be classed as superior to Items like Squirt Gun and Hose. Additionally, since Bees and Hummingbirds provide a doubled growth rate benefit, with this Item they can also be considered somewhat superior to other methods. However, it's key to remember that Trophallaxis poses no benefits towards Fruit Trees, making other watering methods more preferable in that regard.
