Bill and Ivan, the Serpent and Garden Base 4 dominate the South Garden's quiet, grassy realms. Though often prone to a spot of vandalism - courtesy the Vulp aliens - Garden Base 4 remains a low security area. Just north of the dustbins lies the Serpent's corner - a singularly disgusting area, full of broken egg shells, fish bones and rotting mice tails, though not to be missed if you happen to like garbage. Finally, when they're not arguing or being moody, Bill and Ivan keep an eye on the small lawn for me - they're just great for finding lost tennis balls - and we lose about six or seven a week!
