Butterfly Creek animal keeper Roberto Lapinski said Cricket had been kept with dry grass to eat, so was keen for a drink. Because the insects could drown in water easily, they preferred to drink from oranges.
He placed two orange segments in front of Cricket sporting the flags for the competing countries on toothpicks.
The flag in the orange that Cricket went to drink from would be the victorious team.
Cricket spent a while deliberating when the New Zealand flag and the Sri Lankan flag were on show in front of him.
In a decisive move, he drank from the orange then hopped to the top of the New Zealand flag.
Cricket was more hesitant over the England and Australia flags. He went to the orange with the Australia flag, stopping to lick his feet along the way. Maybe he just did not want to see Australia win.
Butterfly Creek spokeswoman Katie Cameron said Cricket would be making his picks for all New Zealand and Australia games, and some of the more exciting match-ups from Pool B.
