In what might be the most adorable Twitter battle of all time, zoos across the country faced off for a "cute animal tweet off" on Wednesday, flooding the social media site with images of koalas, otters and baby animals of all sorts.
The battle started after Smithsonian's National Zoo in Washington D.C. announced the birth of a gray seal pup with a photo of the newborn, Mashable reported.
Twitter user and Virginia resident Sarah Hill saw the post and issued a challenge to her local aquarium.
Not to be outdone, aquarium officials responded with their own cute animal contribution.
