You can meet Signal during the event (31st August 10 am - 5 pm) in the Planetariums lobby, which is freely accesible.
If you spend lot of time geocaching, you have quite a big chance to see a sympatic green frog with antenna on his head. His name is Signaland he's the official mascot of Geocaching.
Signal was born in early years of Geocaching and he symbolizes the connection of nature and technology. The community of players has taken a liking to this mascot and since then, he often appears on Geocaching-related items, trackables, and as a living mascot at mega- and gigaevents. If you see him, don't forget to write down his tracking code and log this rare moment. If you're lucky, he will give you a small gift.
