But more specifically complete a “potd” aka party of the day. Which can be found on the potd thread in forums or ask campus which party it is daily. Or complete a cat cafe/pizza bikini party (your stats are too small for the premium hunt parties tho) and upon completion you’ll gain Easter eggs of various colors
I've noticed that green easter eggs drop more on POTD, blue easter eggs on PPOTD, and pink easter eggs from premium parties. Although, there are instances where you get one or two of the other eggs as drop rewards after parties.
