Koalas training for photo-op with President Obama, other leaders

BRISBANE, Australia (KGO) -- The world's cutest marsupials are being trained for next week's G20 Summit in Brisbane.

President Obama, Russian President Vladmir Putin and other leaders are scheduled to have photo ops with the animals.

Koalas sleep up to 20 hours a day and are known to be fussy.

Officials are spending 10 to 30 minutes a day training them in meeting and greeting people.

The staff says the number one tip is for people to pretend they're a tree, because that's what koalas are used to.
