Once upon a time, in a dark forest, there lived a grumpy bear.

The grumpy bear was always angry and never wanted to play with the other animals.

One day, the grumpy bear found a beautiful red berry in the forest.

Without thinking, the bear ate the berry, not knowing it was poisonous.

The bear started feeling sick and his body began to ache.

The other animals in the forest were worried and tried to help the bear.

They brought different remedies, but nothing seemed to work.

Finally, after waiting patiently, the bear's body started to heal, and he became less grumpy.
