So last night I was playing on my 7th playthrough of SOTC and for the first time I found the tortoises in the desert on the way to the 15th colossus...I'd never known they were there and I thought it was quite cool the way they went into their shells if you trod on them...Anyway I know there are birds and lizards and fish and obviously the tortoises now that I hadn't known about before...It just struck me that as I'd found something new,still after having played it for so long...Maybe there are other things that I've yet to discover...Apart from the secret garden and cutscenes,etc,has anyone else found any other animals or something similar that I've missed out?

I recently found out there there's bats in the cave to the big sand snake colossus. I haven't checked it out, maybe you'd like to

In C3 of the map, in this pond, there's these huge fish that swim around the center, if you get close to them you can have the character grab onto one and swim with it....
