A dangerous manhole which is skipped in different dimension space

There seems to be a dangerous manhole that may be blown somewhere. If there is a mysterious missing case in the vicinity, this manhole may be the cause.

Image is from below.
It is stamped as "Teleport (TELEPORT)" in manhole. Where will you teleport when you open the manhole cover?

By the way, there seems to be an elephant that has become addicted to manholes in Thailand and can not come out. Maybe this elephant tried to teleport somewhere.
