I am convinced that every one of those small brain Skavens that end up on the back of Stormfiends are all just Smart-ish Skaven Infants that tend to throw tantrums, pointing and shouting "Get this one-thing! Get this one-thing!", sometimes fuming with tears in the process, and then you give it a Warpstone milk bottle and the tiny-thing is satisfied.
still doesn't stop the Stormfiend from piledriving you though
