It seems the king of the ocean has a sweet tooth.
A man dressed in a blue and white shark onesie was one of two people who held up a petrol station near Christchurch overnight.
The pair made off with a haul of confectionery around 2:20am, after threatening BP Rolleston staff - armed with a hammer and a knife.
At approximately 2:20am this morning two men entered the BP in Rolleston, Canterbury, armed with a hammer and a knife.
Polie said they smashed a glass shelf which startled the attendant, who retreated to the staff room, where another colleague was having their break.
The store attendants have been offered Victim Support counselling.
Police searched the area but failed to find the pair.
One was described as wearing a blue and white shark onesie, a grey cap, black gloves and socks, and had a dark blue bandana covering his face.
The other was wearing a black hooded sweatshirt, black rugby shorts, a black baseball cap, sunglasses and a blue bandana around their face.
Police would like to hear from anyone who may be able to identify the men or may have seen people wearing these clothes in the area.
