Why isn't my uzi farm working?

[✚ Mariel ✚]

So angry trappers spawn on jungle grass right? Is any size of grass sufficient?

This is what I have built:

Grid of mud with jungle grass underneath for angry trappers to spawn on, grey brick corridor that turtles, derplings etc cannot spawn inside, lava above so that enemies outside will burn to death

Thing is, I'm only getting angry trappers spawning outside the farm and I see them on the very edges as I move back and forth. Why is this? Are the squares of jungle grass not big enough for trappers to spawn?

I think the farm can only be done underground.

Angry trappers rarely spawn above ground. Build it underground.

I don't even think the angry trappers drop uzis on the surface

I remember my old playthroughs. I did it on surface. Near 45 minutes of farming.

Oh boy, after farm I screamed so hard. A scream of joy.

Yeah I think they can drop uzis on the surface I've seen lots of threads saying it

Here's the new functional farm:

It seems angry trappers spawn on flat surfaces that have at least 5 squares free above them. Upper corridor is 5 squares tall and coated in bricks so I can ride my unicorn to quickly navigate. Horizontal platforms below for trappers to spawn on. Lava at the bottom for other creatures to fall into through chutes at either side of the platforms. Lava on the rooftop and in basins on either side of the building outside to kill other creatures.

As an added bonus, nimbus spawn during storms and burn on the rooftop, I can gather the items through the roof because the lava isnt deep enough to destroy them. Werewolves also die.

Wraiths spawn at night but they cant hover up 5 blocks so they end up getting trapped below me

Current strategy is to just sit in my safe room for 5 minutes then every so often kill any trappers that have spawned

Angry trappers spawn all around:
