sometimes when a character is frustrated or has failed to do something, a
cloud made of moving squiggly lines will form above their head (it's somewhat
of a common trope in video games that use speech bubbles too.)

Yes, this pictorial rune has the name: _twirl_.

These _pictorial rune's_ originate from Forceville's categorization, which
