"We'll be safe!" is almost as bad as "what could go wrong?"
Well, the terrain might be troublesome for the Bothare, since they need the wagons, but wouldn't it be a little easier for the Kitik, since they can easily fly over any obstacle? Or for that matter, take on any number of shapes that could possibly help get the wagons past bad terrain. This would be a really good opportunity for them to work together and get to know each other better in the process.
Someone's precinct today ;)
