Spawn Egg Warning is a client-side mod that adds a warning tooltip to spawn eggs whose mob has a certain amount of health points.
The hp threshold is 100 by default but it can be adjusted in the config.
I made this mod for modpacks where it is possible to obtain spawn eggs in survival, to warn the player that the spawn egg may produce a boss or similar.
This mod should work with all spawn eggs including modded ones and ones that contain entity data like adjustments to the max health attribute.
