Snark I[]
The Snark I is a HEAVEN vessel that is used to test the first wormholes. It makes 8 transits, with 3 mannys on board. Bill also uses it to defeat what appears to be Thoth’s escape attempt from Skippyland, by firing a lightweight container with a wormhole inside at the wormhole Thoth was escaping through, it causes an explosion that destroys the wormholes, Snark I, and Thoth's HEAVEN vessel.
Snark II[]
Bill constructs a second test vessel after the Snark I is destroyed.
