I was walking in the swap on my rex when all of a sudden that popped out of nowhere gave me a jump scare, I ran first bcs i didn't know what it was or was familiar with it but then I noticed it barely did damage to my rex so I killed it, and my rex almost got knocked out bcs I panicked and ran b4 realizing I can kill it, got the orb thing, not using it on my rex tho I'll get a trike and pump it with HP and going back to that same swamp as one of the tips here said, i got lucky not knowing what the orb was and js picked it up and went here for info side note reason why I was in a swamp with a rex was bcs the mountain I wanted to get to, to gather crystals was js across I did not expect that thing tho
