Humming, hovering jewels of the garden.
Always on the hunt for nectar!
How to get
Originally Hummingbirds stickers were exclusive to Retro TradeFest! - 5x stickers by completing Tier 9 of April 2018 Retro TradeFest and further stickers by completing Retro TradeFest Bonus Tiers.
Hummingbirds stickers are no longer available in Retro TradeFest Bonus Tiers. They are currently only available at the Pet Sanctuary Sticker Shop by purchasing Bronze or Epic Chests. Hummingbirds require 30 stickers to adopt.
