One day Olaf was feeling sad because he realized he did not have a brain.

He just wished he could be like a normal person.

He wanted a Hippocampus to hold all his long term memories.

Then he could remember all the memories he made with his friends.

He wanted an Occipital lobe to help him interpret visual information.

Then he could remember all the friends he had met before.

Samantha? I don't know a Samantha.

But Elsa warned Olaf that if he got a brain, he would also get an Amygdala, which is the fear center of the brain.

Olaf said that was okay because sometimes fear is good at keeping you out dangerous situations.

So Olaf's friends took him to the magic trolls. The trolls used a magic potion to give Olaf a brain.

Olaf had never been happier!

Now Olaf had a cerebellum, which helps with motor skills.

He wouldn't lose his balance and fall when he was walking anymore.

He now had Pons, which is important for sleeping, dreaming, and waking.

Now Olaf could wake up on time and stop oversleeping.

Olaf now had a temporal lobe, which aids in language comprehension.

Now he could understand all his friends better when they talked to him.
