The Idea Bulb
is a visible indication to the audience that someone has had a bright idea
Sometimes, though, the idea will be a sound notion
, so we hear the Idea Ding
It's a simple one-note Sting
sound made on a xylophone or glockenspiel or something else that sounds light and metallic.
Often appears with its Sister Trope Idea Bulb
. Also related to Audible Gleam
. Compare Palm-Fist Tap
for a Japanese Media variant.
The same sound is often used for Love at First Sight
, but that's a different trope.
- Happens in-universe in the Gumbles and Bottersnikes books; whenever Tinkingumble has an idea, everybody can tell.
