Krenko, Mob Boss + Skirk Prospector + Thornbite Staff
Overview
With Thornbite Staff attached to Krenko, Mob Boss and Skirk Prospector on the battlefield, you can loop: tap Krenko to make Goblin tokens (it counts every Goblin you control) [Ruling 2012-07-01], sacrifice a Goblin to Skirk Prospector for 
(you may sacrifice any Goblin you control, including Skirk itself) [Ruling 2022-12-08], which causes Thornbite Staff’s triggered ability to untap the equipped creature (the Staff untaps the equipped creature when a creature dies) [2008-04-01] so you can tap Krenko again — repeating this produces arbitrarily many Goblins and arbitrary red mana. The Equipment rules about what is the equipped creature apply .

The Equipment rules about what is the equipped creature apply .Step 1
Ensure Thornbite Staff is attached to Krenko (so the Staff’s "Whenever a creature dies, untap this creature." will untap Krenko as the equipped creature) [2008-04-01].
Step 2
Have at least Krenko and Skirk Prospector on the battlefield (that is at least two Goblins including Krenko), and Krenko must be untapped and able to be tapped.
Step 3
Activate Krenko’s 
ability to create X 1/1 Goblin tokens, where X is the number of Goblins you control at that moment (Krenko counts itself in that total) [Ruling 2012-07-01].
ability to create X 1/1 Goblin tokens, where X is the number of Goblins you control at that moment (Krenko counts itself in that total) [Ruling 2012-07-01].Step 4
You now control many Goblins (including tokens). Activate Skirk Prospector’s ability by sacrificing a Goblin to add ; you may sacrifice any Goblin you control, including a token or Skirk itself (but if you sacrifice Skirk you lose its future ability) [Ruling 2022-12-08].
; you may sacrifice any Goblin you control, including a token or Skirk itself (but if you sacrifice Skirk you lose its future ability) [Ruling 2022-12-08].Step 5
When that Goblin dies, Thornbite Staff’s triggered ability will untap the equipped creature (Krenko) when the triggered ability resolves, changing Krenko’s tapped status so you can use its ability again [2008-04-01] .
ability again [2008-04-01] .Step 6
Repeat: tap Krenko again (it now sees a larger number of Goblins than before in subsequent iterations), produce more tokens, sacrifice another Goblin for , let the Staff untap Krenko, and so on.
, let the Staff untap Krenko, and so on.Step 7
Because each loop multiplies/grows your Goblin count (Krenko’s creation uses the current Goblin count, which increases as you repeat), you can repeat indefinitely to produce arbitrarily many Goblins and arbitrarily much red mana.
Resolution
Provided Thornbite Staff is attached to Krenko and Krenko can legally be tapped (e.g. it does not have summoning sickness), Krenko + Skirk Prospector + Thornbite Staff is an effectively infinite combo: repeated sequence of tapping Krenko to make tokens, sacrificing a Goblin to Skirk for , and letting the Staff untap Krenko produces unbounded Goblin tokens and red mana. The ability that counts Goblins includes Krenko itself [Ruling 2012-07-01], the sacrifice may be any Goblin you control (including Skirk Prospector) [Ruling 2022-12-08], and the Staff’s triggered untap is the effect that allows Krenko to be tapped again after a Goblin dies [2008-04-01].
