1. tablet or iphone app only works on some devices; it is not essential however
2. the beast is capricious
3. put in a closed bag by car, she did not fall asleep: she believes that tickles and talkative throughout the trip ... it can be a little long ... (put it in the trunk? )
4. the beast "change" and can become love-love or downright bizarre kind aggressively uncool. The first time it happened my son (8 years) was scared and had to insist that he return to the beast. So be careful with small children !!!
5. do not forget to buy batteries and have a Phillips screwdriver to insert into the beast
Finally an excellent game with flaws (some would argue that these are necessary features and not defects ... up to you!)
