Long queues formed outside McDonald's outlets again, thanks to Gru's minions from the Despicable Me movies.

The fast food chain launched a series of palm-sized minions on July 11 in different designs which were given free with every Happy Meal bought.

The sale of the last set of three minions - yellow, pill-shaped creatures which spew gobbledy-gook in the movies - started at 11am on Thursday.

A snaking queue was spotted at 10.40am outside the McDonald's outlet in Ang Mo Kio Ave 3.

The queue was reminiscent of the Hello Kitty craze last month. Some queues then had 200 customers, all wanting to lay their hands on a limited edition Singing Bone Hello Kitty toy with their Extra Value Meal.

The restaurant's Hello Kitty promotion also caused mayhem in 2000, when there were reports of fights and injuries.
