Chopstix and The Dragon
Chopstix is a blue-and-black panda whose family was cursed hundreds of years ago in ancient China. Because of this, he is constantly being plagued by The Dragon. Chopstix is the only character who can see The Dragon, as he is invisible to everyone else. This makes it easy for someone to assume that Chopstix has made trouble when he was trying to stop The Dragon.

The Dragon is a red dragon with a moustache and goatee, antlers, serpentine body, and a flaming tail. He has plagued Chopstix's ancestors ever since they were cursed. He is known for making trouble and getting Chopstix blamed for it (similar to Lammy and Mr. Pickles). He is a magical creature who can change size, warp himself to different places, breathe fire (sometimes ice), and is immortal.

These two take place of Lammy and Mr. Pickles.
