What are the metaphors in Raymond’s run?

A metaphor is a figure of speech that makes a comparison between two things that are unrelated or different while still sharing a common characteristic. It is possible to make the comparison without using the words "like" or "as." If either of those words is used, then it is a special type of metaphor called a simile. "Raymond's Run" uses similes and "normal" metaphors.
In the fourth paragraph, Squeaky is telling readers about her brother, Raymond. He is mentally challenged, and he has an active spirit and imagination. We are told that he pretends that the "curb is a tightrope," which is a metaphor. Later in the story, Squeaky tells her readers that the city is a metaphorical "concrete jungle."
During Squeaky's race, she looks over at Raymond, and readers get a sentence that contains two similes that are describing Raymond. He is first compared to a gorilla and then to a dancer.

Then I hear Raymond yanking at the fence to call me and I wave to shush him, but he keeps rattling the fence like a gorilla in a cage like in them gorilla movies, but then like a dancer or something he starts climbing up nice and easy but very fast.
