Ben 10

S03:É10 - S03:E10 - Monster Weather

Max takes the kids to a drought-stricken Chicago to see his favorite golden-oldie band perform at a huge music festival. Once there, our heroes cross paths with a deranged weather man who programs his robotic "weather assistant" to actually make it start raining. When this backfires, the robotic assistant ends up creating a trio of terrifying weather monsters to wreak havoc on the city. It's up to Ben to go hero to destroy these weather monsters one by one.
