Slimed

With a voracious need for glass, sand mining is a pretty regular activity.  What was not regular today was the green, gooey stuff dripping from the ceiling.

Ew.

Climbing back upstairs to investigate, I carefully pulled a block of wood out from where the sound was loudest.

That definitely explains the goo.  It also brings to light a potential breach in my perimeter defences.  When I redesigned the greenhouse to take advantage of an overhead water pool, it made a one-way gate right into my underground base.  Granted only something one block wide could fit through the gap, but some rather nasty mobs fit the bill, like this guy, who was not going to make it easy to repair the breach.

As if to confirm my worst fears, a couple of mini slimes dropped in while I was attempting to repair the breach from below.  This wouldn't do - I had to get that hole capped, and fast.

Between the Creepers and the Slimes wandering around on top of my oh-so-thin layer of glass protection, I was feeling mighty nervous about a potential stealth invasion.  Trying to place a block above the water stream from below as proving impractical, so I would have to make an overland trip to secure the roof.

Which was going to be more challenging than you might expect.  Besides the green menace to the left, I had at least four spiders jockeying for position above my head.  Never had the dozen or so blocks from ground floor base to roof seemed so far.  Carefully inching my way out, temporary dirt walls held off the arachnids until I could drop a glass cap on the water hole.

Getting back inside was almost as harrowing as making it out there, juggling between sword flailing and hasty block destruction.

It was definitely worth it though.  Now if I could just find that elusive Spider spawner...
