During the theft of the corination stone at Westminster Abbey, Hoppey the kangaroo and his trainer are right next to the Chan kids, who are pretty clearly a piece away from the throne and thus the stone. When the lights go out, you can clearly see the kids along with Hoppey and his trainer. None of them move from the spot they were in before the lights go out. Thus the question is raised as to how the trainer could have stolen the stone and put it it Hoppey's pouch if the two never approached it when they were supposed to steal it. Big mistake making these two steal the Stone of Scone in the dark when the audiance can clearly see them not move during that entire period.
