People keep wanting a map of the Louvre despite my assurances that it's just like the one above, but much simpler, and the excellent or the which looks just like mine, but has graphical cues.

It helps if you know your artists.... http://www.warehouse23.net/files/louvre.pdf

Ancient Crimbo Troll:
Cage Match: ?
Scavenger Hunt: ***
Obstacle Course: ?
Hide and Seek: X

Combat effects: volleyball seems to work as advertised.
Whelp-like effects: seems to be ~40-50% of the time, either HP or MP, range as follows:

14 lb:
Nothing: 7
HP: 9,10,11
MP: 7,8

15lb:
Nothing: 13
HP: 8,10,12,12
MP: 7,9,12

This is significanly worse than 40% of the Wiki's whelp, I've not tested myself.

If it scales directly with weight, and the MP and HP distributions are the same, a troll is worth approximately 0.12 MP/lb/combat. At soda water rates, that's 2.1 meat/lb/combat, which is better if the average base meat drop rate in a zone is less than 42.
