I recall the ogre being under-CRed, so that's probably not the best creature to use for comparison purposes. But I'm really not good at judging CRs at all -- it's been far too long since I ran any 3.x monsters.
I'll let a coin toss decide instead... and the coin seems to think that the ferry turtle should be CR 3.
Ha! Victory is Mine!! Random Numbers are My Friend!!!
Oh and Updating Working Draft!!!!
I Think That's Enough Exclamation Marks!!!!!
