Arizona - Dog brothers Tub and Blue have been landing viral hits for months with their mostly pitiful attempts to fish a tennis ball out of the pool.

On TikTok, the Golden Retrievers' account has 1.1 million followers and an accumulated 46.6 likes and counting!

Most videos on the popular social media account show the pups staring hypnotized at their beloved tennis ball lying on the bottom of the pool, so close yet so far out of reach.

Obviously, the toy is gone forever, right?

Cats Cat's brazen theft of porch groceries sparks hilarious chase!

The optical distortion of the water doesn't help matters, making the ball look like it's fallen into another dimension and causing evident confusion.

Other videos do show how they're able to succeed in retrieving the ball when it floats on the water.

The doggie brain trust has yet to figure out the puzzle that is underwater objects, however.

Despite their failures, the dogs often still try to move the toy with their minds alone in subsequent videos – although this strategy tragically hasn't worked thus far.

Maybe one day they'll figure out the mysteries of the pool. Until then, they look pretty darn cute trying. Good luck boys!
