Joseph "Joey" Beetles is the baby brother of Numbuh 4. He is also the world's greatest dodgeball player ever.
Joey is a main character in Operation: D.O.D.G.E.B.A.L.L.in which the episode's villain, The Dodgeball Wizard, triumphs over Numbuh 4 (whom he mistakes for the world's greatest dodgeball player only knowing that the greatest dodgeball player is "the one called Beetles") in a game of dodgeball.
Only to discover that the greatest dodgeball player in the world is actually Joey, The Wizard engages Joey in a spectacular game of dodgeball throughout the city, which baby Joey ultimately wins. Joey is probably a bit less than 1 year old or as he appears.
His name "Joey" probably comes from the Australian slang word "joey", which means baby kangaroo, making him and Wally named after marsupials.
