Cartoon Bubble Sound Effect Page
Consider the trope of the "thought bubble." A character has an idea, and a clouded bubble appears above their head. Often, this appearance is accompanied by a soft, ascending "bloop" or a shimmering, liquid sound. When the thought is finished, the bubble pops—sometimes literally, sometimes figuratively. The "pop" sound effect serves as a punctuation mark, a period at the end of a sentence.
