Considering Lauftroll's build, I'd rather bet on a version of Whack-a-Mole with some huge battle hammer.
(we can save the Benny Hill theme for the Blorptroll)
The Lauf is a really slow troll if the spjoing function doesn't count, by the way! That's why it hides in walls and ambushes its prey, it can do quick leaps forward and even faster vacuum cleaner cord retreats but out in the open it would be slow and clumsy. It's great at climbing but not the fastest at that either.
Whack-a-mole with holes in the wall, now that I could totally see happening...
