My Naga and Wavern. They're broken lol.I love to close Storm Skyresssss and Attmmosoososos.I guess Phosphos is hard to close... It simply pops out when I close it...Pyro and Midnight are hard too if you aren't close the 4 things together at a same time.Spitarm always pops out too.As well as Spyderfencer....
Well if you're using that as annoying then just add Freezer and Fencer to the list.
Yeah, they are irritating, but not hard.
