Crazy Frog (also known as The Annoying Thing) began in 1997 as a widely-shared audio file of Swedish teen Daniel Malmedahl imitating the two stroke engines on his friends' motorcycles. In 2003, animation student and fellow Swede Erik Wernquist used the sound to create "The Annoying Thing," a minute-long computer animation test, pairing the sound up to the design of a grotesque frog-like creature. Wernquist credited the audio to "anonymous" at the time, but later credited Malmedahl when he saw the animation and gave Wernquist permission.
A year later, the two creators sold the character and sound to ringtone service Jamster who rechristened the character "The Crazy Frog," turning the sound into a hugely successful ringtone. The character was popular enough that Jamster eventually produced a techno cover of Harold Faltermeyer's "Axel F" with samples of the sound, complete with a music video. It was popular enough to keep Coldplay's "Speed Of Sound" off the #1 spot on Billboard and eventually warranted two albums worth of similar covers. A cover of the synthpop classic "Popcorn" had some success, but it was mainly limited to Europe.
After a long period of inactivity, his YouTube channel (found here) suddenly became active once more in 2018, with a documentary on the character's creation being released and new activity popping up on various parts of his account. Whether this is hinting at a possible return for the odd amphibian or not remains to be seen.
The Crazy Frog contains examples of:
- Amazing Technicolor Wildlife: Frogs aren't typically blue.
- Animals Lack Attributes: Averted, at least at first.
- The original animation of the character gave him a very visible penis. It remained all the way up to the "Axel F" video until Moral Guardians complained and it was digitally removed.
- Along with the removal of the Frog's penis, the "Axel F" video was altered to remove the explosion at the end.
- Cover Version: Virtually all of the Crazy Frog's songs were covers, and were merely techno versions of popular songs with samples of the original "Annoying Thing" sound peppered rhythmically throughout.
- Half-Dressed Cartoon Animal: The Crazy Frog.
- Killer Robot: The robots that are sent to hunt the Crazy Frog in "Axel F," also appearing in various other music videos.
