A couple of Colorado women were recuperating after a moose attack northwest of Denver over the weekend.

"All of a sudden, I looked up and he was looking right at me and grunted and then charged," Jackqueline Boron told CNN affiliate KDVR . "I tried to get up, and he kept coming back and stomping on me."

"When I fell back he got me here," Boron said, pointing to her arm. "Then, when I curled up forward, that's when he got me on the head."

at depths of up to 1,200 meters off the coast of Australia where it feeds on crabs and lobsters. It's under threat as it often gets caught up in fishing nets... but you wouldn't want to eat it.

It's the only flightless parrot in the world and has very muscular thighs, according to the British Science Association. On the left is former New Zealand Prime Minister Helen Clark.

The attack left Boron with staples in the back of her head, 15 stitches on her leg and four broken ribs, KDVR reported.

Ellen Marie Divis was also stomped on by the moose, but was able to get away to find help.

"I heard 'help me, help me, help me,'" neighbor Chris Hockley told KDVR. "This lady comes running up to her house and she's covered in blood."

The sheriff's office issued a warning after the attack.

"If you encounter a moose: walk away from it -- DO NOT walk towards it; moose are agitated by dogs; make sure your dog is on a leash, control the dog(s) and walk away," the warning said.

Lesson learned, Boron said -- don't mess with a moose.

"Don't hike (when) you know ... there's moose out there."
