It's novel and has that early-2000s gross-out humour for kids attitude, but it's a fairly run of the mill collect-a-thon at the end of the day. Irritatingly most of what you need to collect can only be seen and picked up in the greyscale first-person view, which removes some of the appeal of the otherwise decent looking environments. The ending certainly takes things up to 100 though. Worth a curiosity check, and it's only about 6 hours long to collect everything if you're willing to stick with it.
