The horse was running fast on a paved road. Then, she was feeling hot, she slowed down and stopped on the side of the road.
Horse (Panting): All this running's making me so parched for water! I'm so sweaty!
The horse walked back on the road to go find a barrel of water to drink.
There, she saw a big barrel of water to drink. She stopped, pulled the cork out with her mouth, and drinks the whole water out of it.
Moments later, her belly is bloated, she is unable to run back home, but instead, she decides to walk home and rest.
She walked home and laid on her back to rest.
After that, her belly is normal again. She is happy to be skinny again.
