Of course your average kiwi tramper when chancing upon a giant block of Milky Bar chocolate would immediately suspect that a) something was up and b) it was a commercial being filmed.
Thus the attempted stunning by the savagely transformed snail/chocolate would be unsuccessful due to the Kiwis being on their cellphones to their agents and therefore being protected by the invisible force field which protects that man on the bus who has arguments with his spouse via mobilephone on the way into work on the bus."I don't know what kind of dog it is.
