In the Groove

Why does this snake try to stay in the grooves between the blocks in the wall?

Does the support of the sides help him move?

Why did he try to climb up the wall?

He ended up coming back down to his original track almost immediately.

It seems like wasted effort.

Of course, it was a nice photo opportunity for me.

Groovy!
