Stork prided himself on his traps. They were elegant; nothing sloppy that could set it off by accident, too soon, and/or miss their target. They were ingenious; no two traps were the same, forcing the intruders off-balance while the rest of the Storm Hawks dispatched the threat. And most important of all; they were hidden so an intruder could fall victim to three at any give time and never know the danger.
So when Repton fell into Finn's practical joke, it was only natural that Stork felt a little annoyed.
