Parrots

Red's Parrots are Red's pets which he summoned between the two episodes, Build Battle - AVM Shorts Episode 17 and Texture Pack - AVM Shorts Episode 18. They first appeared in Texture Pack - AVM Shorts Episode 18, in their Blue and Green form.

Story
In Texture Pack - AVM Shorts Episode 18, Yellow messes up the blocks folder in the Minecraft directory and randomizes the textures. As a result, the Parrots' textures are messed up, and they lead Red towards Yellow to bring back their old textures.

After then, they understand they can change the texture to whatever they want. A few minutes later the Green parrot transforms into orange, and the Blue into purple.
