What two words did make squiggle?

This is a bit of a trick question! "Squiggle" is already a word, and it doesn't typically come from combining two other words.

However, you could think of some playful combinations:

* Squish + wiggle - This creates a sense of the movement and shape of a squiggle.

* Squeal + giggle - This evokes a playful and silly image, which could be associated with a squiggle.

Ultimately, "squiggle" is a fun word on its own!
