Even though they appear friendly, they are responsible for hundreds of bag, wallet, cash and mobile phone thefts during every summer. Once they have stolen from a victim they pass it very quickly amongst themselves, so even if you realise it has happened it will be way too late.
The merchandise they sell (Hats, Balloons, glow sticks etc.) is just a front for their more lucrative schemes. The children (sometimes as young as 4) are the worst culprits of this and they quite often work in teams and play massively on how cute they are. One of their techniques is surrounding you and trying to jump up and appear to innocently hug you while the other children are opening zipped up pockets and bags and removing the contents without the victim’s knowledge – THEY ARE EXTREMELY GOOD AT WHAT THEY DO! Be Careful!
