Ok, they're maybe not the worst (oil rig, pipes and stack of rice somes to mind), but they're not doing anything for me. Zen garden is a bunch of rocks in sand, geyser sounds so much more cool than it really is, lol.
I have the following villagers:
Biskit: Lazy
Snake: Jock
Peewee. Grumpy
Cesar: Grumpy
Rodney: Smug
Wendy: Peppy
Blaire: Snooty
Gayle: Normal
Muffy: Uchi
Muffy, Rodney, Snake and Peewee has suggested pretty much every one of those.
Doesn't the Geyser spray out continuous water?
