A woman near Adelaide had the best tree-topper of all time-at least for a day.

Amanda McCormick found that her Christmas tree had a new ornament after a live koala wandered into her home and snuggled up the branches of the white pine.

Lucky for the internet, she took pictures before calling a wildlife rescue group, 1300KOALAZ.

"Our hotline operator took a call," the charity wrote on FB. "At first she thought she was the victim of a prank call."

They merrily reported that the koala was "desperate to get in the Christmas spirit."

Amanda, who lives in Coromandel Valley in southern Australia, is not alone. Dee Hearne-Hellon, the co-founder of 1300Koalaz, says koalas are occasionally known to sneak into houses.

Perhaps, especially, when there's a pretty tree to climb.

The juvenile female was released into the neighborhood, which is in a region of habitat perfect for koalas, and scurried up a nearby tree.
