I thought that the kid in that planet (starts with an I...) was cool. It's weird how the people on that planet thought that they were being cursed by a ghost. Too bad LEGO's probably never going to make any of those minifigures...
Those bomb squad clones and the little droid in "The Blue Shadow Virus" also looked really cool.
EDIT: The kid's name was Jaybo Hood, the spirit's name is Drole, and the planet's name is Iego (looks like "LEGO" )
