You'll see a lot of these guys in photos over the coming days so here is an introduction -
This is Webster. He is named after PFC David Webster from Easy Company. David was into sharks - so much so he wrote a book about them.
This is Joe. He is named after T5 Joe Liebgott, also of Easy Company (and a friend of Webster's).
This is Geoshark. A late addition to the shark contigent. I found him in a cache a few days ago and he had to come with me. As you can see he is actually a finger puppet.
