Pororo

Season 1

In "We're Friends!", Pororo was going to make a snowman, he fell down and found an egg and brought it with him into his house to cook a fried egg (as shown in the thought bubble). When Pororo wanted to break the egg but it’s already too late for it, unfortunately, because of Crong finally hatching in his egg. Pororo thought Crong was a monster to scare Pororo. Pororo got scared and he runs away. Crong not realizing what makes Pororo run, he runs off after him. As a result, Pororo understands that Crong is a friendly creature.

In "It's All Right", Pororo visited Poby's house, and played with the ball, until it hit the shelf and Poby's camera is broken, by accident. Pororo and his friends fixed Poby's camera.
