Torug: placid, vegetarian turtle people (they look more like tortoises, but can breathe water), created by some nature deity to serve them on both land and water. Not really suitable PCs, because they have lousy stats. +5 STR & Armored & Water breathing, but -7 AGI, -5 DRV, and -5 PER. Hm. Would a giant version work for a PC? +5 SIZ, +10 STR, Armored (5), Breathe Water (1), -7 AGI, -5 DRV, -5 PER. Actually, the big version could lose the -5 DRV... they'd be the leader types of their race... or they could get +5 KNO for being very old... all of the big ones could be ancient.
The lizard-dog things are from one of the nastier demon realms. There's also a rarely seen version that's intelligent and has a hypnotic gaze attack. Few of them make it out to Menagerie, but those that do generally take full advantage of the fact that most people can't tell them apart from their animal kin.
A Tain-like trap realm. Folks who get hit get zapped into a sealed Realm created solely to serve as a trap. Theories abound as to whether it was created by a god or what and as to whether or not it could be controlled. Folks who move through the affected area often just vanish into it, and very few return.
