Just thought I'd start putting my new vector puppets to good use. That yellow dragon is my version of Bumblebee from Transformers if he was in Equestria as part of my "Autobots in Equestria" line of fanart I've been working on lately.
Bumblebee meets Twilight and Spike in the beginning of this story and is mute but he communicates by blowing electric blue fire out and then a scroll magically appears that has words on it. Initially, Spike does not take to fondly of Bumblebee at first because he's jealous that there is another dragon that knows the magic scroll trick and he thinks Bumblebee is trying to upstage him to get Twilight to like him more. Bumblebee looks nervous because he's scared Spike might find out he's actually a robot in disguise trying to protect him and Twilight but when the secret is revealed and he saves them both from an encounter with Decepticon Barricade, he earns both their trust.
