Give the Stalker ability to fit into small holes to the warden

This idea came up after watching some of kingbdogzs clips of the scrapped "stalker" mob. Now, if you haven't seen the mob, its a really tall mob which was going to have the ability to transform into this small more compact grosser version of itself to fit 1x1 holes, to which i presumed was going to stop players from digging holes down so it cant reach them. even though this version was scrapped, I think that giving his concept to sort of transform is given to the warden, only this time we can make it a bit more scary. for example, instead of having the warden transform into a four legged abomination like the stalker, have it dislocated the bones in its body and dive into 1x1 holes, making gross cracking and slithering sounds when it moves kind of like a octopus that has no bones. this would be a better method then breaking through blocks and gives a horror feel to it, like its doing literally everything it can just to get to you.
