Gumball was the first air to test the animation was May 3, 2008, but when he's show was debut (launch the series up!) in May 3, 2011, all show must have a pilot, except in 3D shows only, c'mon, because PPG, Oggy, WBB, Regular Show, Steven Universe, Adventure Time, Craig of the Creek, Apple and Onion, Summer Camp Island, and more had a pilot too!, but PPG's (Original) pilot name was called "Whoopas Stew", now in series was called Powerpuff Girls, but Oggy's pilot, that reminds me he's pilot show was known as Space Goofs, because the track music was taken from Space Goofs, Space Goofs launch at 1997, Oggy was premiere in "The Secret Episode" was launch at September 6, 1997, and the series will debut at September 6, 1998, and PPG pilot was launch at 1992 only in USA, the series will begin at 1998 in September (same with Oggy tho, except the number day), and Adventure Time's pilot was only available in Nicktoons, now the series was only on Cartoon Network now. the pilot just add some 1 episode only, but the series (for Adventure Time) is done finale for now in 2018, ;( (man i miss them so much), now i'm afraid that in the late year, Adventure Time will be add with reboots!, and technically i most like the Cartoon Network Shows of 2010-2018, because Cartoon Network in now has some awesome tracks tho. The end, that's my long words.
