User blog comment:BannedLagiacrus/Monster Appreciation Week: Bulldrome (4th Gen)/@comment-5020152-20160730234430

So, I just discovered something new about Trolldrome. I was fighting him in Area 7 of the Arctic Ridge, and he accidentally ended up charging into one of the borders (it looked like he was in danger of falling off the mountain). But then Trolldrome actually burrowed into the ground and popped up elsewhere.

Maybe this is like those times in FU where Monoblos/Diablos would fly if they ended up too far outside the borders?
