Creakings are harder to beat but drop something

The pale garden is one of minecraft's most interesting biomes, but it should definitely have some sort of none decorative purpose. The creaking also feels to easy to beat when you consider that you can literally trap it in a box and mine the creaking heart freely. Maybe the creaking heart could spawn new creakings after a certain amount of time, and the first creaking it spawned could be the one that drops something. (Or the creaking could drop nothing but the creaking heart would drop something). Note that this would only happen with naturally generated creakings.

Maybe it could drop some unique kind of seed that grows some sort of special food type, since the pale garden is full of nature, with new flowers, moss, wood, resin, and a tree based mob. The food type could be kind of like a golden apple (although maybe a bit weaker and different) in the way that it could give you effects when you eat it. Maybe the plant could be used for a potion of resistance, since resistance is a strong effect and this would make it an unfarmable potion. This would make sense as well, since the creaking doesn't take any damage and the resistance effect reduces damage.
