Talks to Squirrels/Sandbox

There are times when the heroes come across an alien or an animal whose help they need, but find themselves unable to communicate. Suddenly, The Ditz or the Cloudcuckoolander steps forward and starts talking with it. And the other party responds. Somehow.

Suddenly Communicates In Gibberish refers to a character displaying the unexpected ability to communicate with somebody or something that should be impossible to speak to. The conversation is always done in gibberish, whether that includes beaver talk, Martian talk or anything similar. The skill comes without any prior foreshadowing and is almost invariably Played for Laughs. When asked how they learned it, The Ditz will more often than not respond that they always knew that. The other characters will usually be left aghast and try not to think how it makes sense.

Sister Trope to Suddenly Bilingual. The difference being, Suddenly Bilingual has to do with actual languages, and not gibberish.

 * A variant occurred in Fallout 2: In the first town you reach after leaving home, you encounter a mentally stunted man who with great difficulty tells you to help safeguard some livestock.

Almaz: Princess, you can understand what Mao's saying?

Sapphire: No, I just thought it'd be easier if that was the case."
