Kenneth
He grunted, hissing faintly as he squirmed under their grasp, trying to make it more difficult for them to be more stable. His eyes sparkled as an evil idea began to take hold of his mind, his eyes flicking towards their talons.
"Let's see how you deal with this..." He giggled, before biting his tongue in order to flick his tail up and landed the stinger on the back of their left back leg. He didn't exactly fully sting them, but the fact that he had fully landed a shot would probably terrify anyone enough to the point where he could escape...
Willie
He hissed in alarm, raising his rear leg as he prepared for the venom to sweep through his bloodstream. His eyes were full of panic and he stumbled abit. He craned his neck to check his leg, all-too soon realising it was a trick, his face scrunching up into a snarl. The distraction had cost him though...
Kenneth
He easily wiggled out of their grasp and hopped a bit away from Dingo, his tail wracking the bookshelves. Pain shot through his entire system but he barely kept himself up as he took deep breaths to try to ward the pain off. He then chuckled, smiling evilly at them as his wings shuffled. 
"You should've know better to pin the Sand'Wing's best weapon when *You're* A Sand'Wing yourself." He mocked, cackling in laughter as he slowly walked back, slowly towards the exit. If he could get out, he could probably get a guard or two to stop Dingo.
