You need to fill the lake first. Also, go to page 7 of the VV5 section and look at the thread titled 'how to get rid of the rascal forever(glitch)'.

I would link the thread itself, but thread links aren't working right at this time.

The rascal definetly gets the most complaints around here, so yea, you aren't alone in that feeling of the rascal being annoying!
