Shadow of the Colossus Tips

Lizards increase your energy bar
If you happen to run across a save alter search around for a lizard with a white tail. if you eat it your energy cirlce will increase slightly. There are also several "secret" white tailed lizards found in areas besides alters. A few I know of:
1. When you enter the southern half of the land go east as far as you can go. There should be an alter with a large tree near the cliff overlooking the sea. If you look down the cliff from the tree you will see a ledge with a lizard on it. *warning* if you jump down to get the lizard you will seem stuck. Look to the north and you will see a ramp you can jump down to.
2.Near the broken seal area there is a rock formation that obviously isn't natural. a lizard crawls amongst the rocks.
