Golden Egg #60 is located in level 1-7 of Angry Birds Seasons Tropigal Paradise. The Golden Egg is completely hidden by a pile of leaves at the very top of the level. Luckily, once you now where it is it’s easy to obtain with Chuck (Yellow bird). This level was released in v5.1.0, the “Tropigal Paradise” update.
Thanks to @mighty-red-1 for helping us locate this Golden Egg. It’s nice to see Rovio hiding them completely again.
