Unique drop for the new mega caveworm

[stanroberts007]

the mega caveworm doesn't have any unique loot, for an enemy that has 5000 health this feels a bit weird to me, so an idea i had to add to the new worm without adding anything too powerful, is making a new bigger glow berry, the original idea i had is that when consumed it gives the light of the glow berry but double the range, and with a longer time, similarly the cooked food could be a more powerful glowberry mousse, the other idea is that it could glow on the ground, which could be combined with the new ichor storage container to make a small-medium light source. another idea is to combine the glowberry with a lunar rift item to make a much better light source (could be infinite) to give a cave/nightmare version of the misery toadstool/celestial champion infinite light source. 

of course these are just random ideas to add a unique drop to one of the new mobs, that doesn't feel too out of place for the new mob.
