Random Paw Block in Sand Zone

If you get to the place in sand zone with a heck-ton of birds and fall down, there is a single block you can walk through that goes nowhere, does anyone know why this is here?

 

It's to remind you about paws

 

paws your game and think about it

 

You found a clue! Find two more and figure out what Blue wants to do for the day!

 

Pixel probably put that there because it was an obstacle of sorts, that or because he wanted people to overthink its meaning of being there.

 

most likely a hint that theres a dog

 

Because it was a dog zone before getting filled with sand.

 

I have a theory...

 

The sign next to it tells you that some blocks can be passed through I believe, so if you look around you see the one different block and think hmm, what if that's the thing. quote jumps in and passes through. tadaa, now find one with stuff behind.
