If you spend a bit of time geocaching, chances are you'll see a frog with some metal attached to his head. This is Signal the Frog, the official Geocaching mascot.
Signal was created in the early days of Geocaching.com as a way to represent the combination of technology and nature. Since then, Signal has become beloved by the geocaching community and appears on geocaching-related gear, trackables—and even in-person at some Mega-Events. If you see him, make sure to give him a high-five and discover his tracking code.
If you'll notice, Signal isn't just a frog, he's a frog with something attached to his head. We searched through the animal kingdom and we couldn't find any other metal--enabled animals besides Signal, so the choice as a mascot was easy.
So, what is attached to his head (one word)?
