Please help I'm almost there.

Explanation:

A million years ago, when dinosaurs were still roaming the earth, our English teacher came into the room and said to us. Look! Running up a tree, I saw a squirrel. Then when we had finished looking out the window to see if we could see the squirrel, she said to us. "What's the problem with that sentence?"

Trapped. A teacher joke.

Then we caught on. There was no squirrel, but there was a problem. Who was running up the tree?

You have the same difficulty. The punctuation is fine. The problem is in

Hope shouted my name, running toward me with a big stuffed animal.

Who exactly is doing the running? It sounds like your name is doing the running.  You have to fix the order.

Running toward me holding a stuffed animal was Hope. As she ran, she was shouting my name. Even that is not totally correct. Let's try again.

Holding a stuffed animal as she ran toward me, Hope was shouting my name.

You can report this as a problem. The punctuation and Capitalization are fine. The order isn't.
