Okay, remember how in the first footage shown of Animated we saw Sari ride a tricycle that turned into a jetpack? It hasn't shown up yet, but I'm not writing it off as a dropped concept-it WAS in the trailer, after all. I think that she gets it after or during the events of 'Megatron Rising'. In 'Survival of the Fittest' she was being taught self-defence against the Decepticons. Now, as it is obvious that eight-year-old-girls stand no chance against giant evil robots no matter how much they know about fighting said-robots, maybe the Autobots decide that running away may be the best strategy, and make the transforming trike for her. Also, am I the only one thinking that it could be a homage to the transforming accessories from the Action Master line?
