growing squashling glitch

[azix]

hey there,

i was doing the event dailies when i had to run away because of low health. however, the growing squashling i was in fight with didn't stop following me. i kited him up to my garrison till another player killed it. actually it was quite creepy being low in health and having an evil grinning pumpkin hunting you forever^^
it seems like you don't have to do anything special to replicate this as someone mentioned the same thing on wowhead already.
