For those who don't know what they are doing in the sack, this can help as a guide...
From a CanWest News Service article: The more (players) stimulate the bunny, the happier he becomes until eventually he begins flying through the air. But Lapis is also an unpredictable creature who needs a variety of sensations. Sometimes, no amount of stimulation is going to work.
I'll give it a try tonight and report back later. ;-)
[Update: I couldn't get the software to work...wonder what that says about my skills?]
