A wizard did it! (playing with a random generator)

[inuyasha]

I'm posting my first one! I also wanted to point out to Eldan that he was correct on his beast's CR, I came up with a 2.9 using the formula I use. So 3 is perfect.

Components: A cask of giant nautilus bones, A component pouch of troll bone dust, a firkin of toad bile [just googled firkin, that's quite a bit!]

In the distance you see something tremendous and froglike, as it hops towards you in great bounds, it's true features have become apparent. It's skin is a sickly greenish grey, it's mouth is adorned with many spike tipped tentacles, and it seems extremely hungry

The batrachian abomination is...unique, this is fortunate as most that cross it's path die rather quick. The beast is nearly impossible to sedate, and it's flesh seems to regrow even if it is killed temporarily.

Combat
The creature lunges at whatever it can and attempts to eat it.

Constrict (Ex):
Those grappled by the Batrachian Abomination take 2d6+9 damage per round as they are constricted by the tentacles coming from it's mouth.

Improved Grab (Ex):
The Batrachian Abomination can, as a free action try to start a grapple if it has hit with one of it's tentacles
