- They brought it to American and in 30 minutes, it had caught up to 500 robbers.
- Then, they continuously brought it to China, this time, 6000 robbers in only 10 minutes.
- And finally to Vietnam, the scientists couldn't see any signals. When they came out to examine ... the robber- catcher had been robbed!!!
