Boulder Bro is the twelfth episode of Angry Birds Toons Season 2 and the sixty-fourth overall.
The Other birds grow tired of Chuck's attention-seeking. That's ok. Chuck will just make a new friend!
Chuck has made a new friend, which is a piece of a boulder with a happy face made out of chalk and it also had arms made out of sticks. Chuck was karate chopping things and training for the boulder, so he made it clap its stick arms. The Blues were watching this, so they decided to play a prank on him: they used the chalk to draw a bored face on the boulder. When Chuck noticed this, he was very surprised, so he drew the happy face again and continued showing off his training. The Blues laughed and accidentally knocked the boulder off the cliff. Chuck got scared and looked down on the cliff. The boulder just turned out to be on an edge of the cliff. Chuck pulled it by one of the stick arms, but it broke off. The boulder fell to the ground, waving "bye" to Chuck. He took off his headband, threw it off the cliff, and started to cry. The Blues felt sorry for him, so they fell off the cliff and got hurt when they hit the ground. They found the boulder, which was not destroyed at all. They felt helpless until they saw Chuck's headband, so they used it to fling the boulder back up the cliff. Chuck was surprised that the boulder came back so he hugged him. In the afternoon, he karate chopped another boulder. The Blues were impressed, so they looked at the boulder, which made a silly face. It turned out that Chuck drew that face, so he started to laugh as the credits rolled.
