Where are the secret stars (Super Mario 64)?

I'm trying to find the remaining secret stars in the game so I can see Yoshi, but besides the one in Peaches room and the one above the aquarium in the first aquatic level room I have not been able to find any others

Can somebody help me out?

Did you try getting 100 coins on all of the courses? You get a star for each one of those as well

Where is the last Red Star Coin located in the bob-omb battlefield? I found the one above the moving platforms, the one in the rocky area near the second cannon, the two near the tree stumps, the one on the mountain, the one under the bridge next to a switch and one-up, and the one on top of the tree on the floating island, but I can't find the last one.

So where is it?

It's on the stump that the chain chomp is chained to. You can also stomp on that tree stump a few times to reveal another secret star.

Where is the secret star in the Haunted Mansion world?
