If Pinocchio says his nose is growing and its not, what happens?

Have you seen Oppenheimer? that.

it starts...

Paradox.

You'll never believe what happens next! Choose your adventure: a) Your Pinocchio isn't the main character in The Adventures of Pinocchio b) Ooh, squirrel!! c) It's not a bug, it's a feature d) It's not a feature, it's a glitch in the matrix e) TIL the Liar Paradox (https://en.wikipedia.org/wiki/Li...)

If Pinocchio claims he's lying, his nose would enter an endless cycle of growing, shortening, and growing again, possibly resulting in a burning sensation from the friction. Eventually, it might even lead to setting him on fire. That's a tragic 'burnout' situation.
