The Cartoon Network Check It 3.0 sign off featuring Gumball, a short channel ident jingle used to close programming and mark transitions on TV.

This is the short sign off ident from Cartoon Network's Check It 3.0 era, built around Gumball from The Amazing World of Gumball. It combines the channel's bright electronic jingle and mnemonic tones with a quick closing sting that signaled the end of a broadcast block. The sound is upbeat, bouncy and instantly nostalgic, with clean synth hits and a playful rhythm that matches Gumball's chaotic energy. Played on its own it works like a TV transition, giving videos a sudden, polished cartoon channel ending in just a few seconds.

Check It 3.0 was the branding package Cartoon Network rolled out in the early 2010s, replacing earlier eras with bold colors, a checkerboard motif, and short musical mnemonics. Sign off idents like this one were played between shows and at closedown, often using characters from current series such as The Amazing World of Gumball, which premiered in 2011. Clips from this era circulate online because viewers who grew up with the rebrand remember the jingles instantly, and creators reuse them as nostalgic endings.

Pro Tip for Usage

✦ AI

Place it right at the very end of a video or stream segment, after your last joke or reveal, and let the full sting play out without talking over it. Do not loop it or cut it mid-jingle, or the sign off effect is lost.

Use Cases

✦ AI
  • End a cartoon edit with an authentic TV sign off
  • Close a Gumball meme video after the punchline lands
  • Signal a stream break like a real channel transition
  • Add a nostalgic Cartoon Network ending to compilations
