Your username: koohikoo In which minigame/server does the bug occur: skyblock Detailed description of bug: upper levell of the shoip there are some spawn eggs but you cant tell what egg is the one of what you want please switch item frames or place signs above telling what egg it is
It's pretty simple to figure out what a spawn egg spawns; the colors of the mob match the spawn egg. For example the ones in your screenshot were ocelot, sheep, mooshroom, witch, bat and magma cube in that order.
This isn't really a glitch or bug. They never added the signs. Also, last time I saw Willy was in the Skyblock shop in the upper level. I don't think they want to put signs. So you could just use google.
I would recommend locking this and posting it on the "Suggestions" section. Since this is not at all a bug, it has always been like that as @Durske1 said
