I got to hand it to WotC, they sure have a lot of weird monsters on hand. Arguably it's gotten out of hand here, though.
Handily enough, odopi have physical stats in the mid-twenties, okay DR, fast healing, free Whirlwind Attack, and useful energy resistances. On the other hand, they suffer from 20 aberration RHD, can't use weapons or tools (other than thrown weapons for some reason), and lack extraordinary forms of movement. To function, your party will need to lend you a hand quite often.
Also, for some reason, WotC thinks Improved Grab, Swallow Whole, and Trample are useful abilities at mid-levels. I can't believe my eyes.
Feyenally, there's the spell-likes which are mostly just bad. At-will feather fall, 3/day Dimension Door and 1/day True Seeing are not very impressive.
Conclusion: -0 LA, hands down.
30 rhd bad, -0 la.
