1 Boba Fett: Well, this sucks.
2 Boba Fett: I had a party to go to tonight.
3 Boba Fett: But now I’m stuck here...
4 Boba Fett: ... being slowly digested over a thousand years.

Here's a great example of how a throwaway line from the Star Wars movies that was most likely to be meant metaphorically has instead been taken at face value and then justified with a ridiculously complicated backstory of lore. In Return of the Jedi, C-3PO translates for Jabba the Hutt: "You will therefore be taken to the Dune Sea, and cast into the pit of Carkoon, the nesting place of the all-powerful Sarlaac. In his belly, you will find a new definition of pain and suffering as you are slowly digested over a thousand years."

Our heroes of course avoid this fate, but Boba Fett falls into the Sarlacc^[1]. It's shortly after this that the above comic is set.

But back to the lore. As Wookiepedia describes, the Expanded Universe background lore on the Sarlacc says that:

Once the victim was swallowed, they fell into the sarlacc's stomach, deliberately being kept alive by the beast and digested extremely slowly for a millennium. The stomach walls were lined with tentacled vessels which punctured and embedded themselves into the prey's skin and muscles before fixing them into the walls. The tentacles then injected neurotoxins into them, causing constant pain and rendering them immobile while being fixed into the walls of the stomach and digested. The vessels also gave enough special sustenance with the sarlacc's blood for its prey to enable them to live for centuries while they were digested.

That's right. Rather than absorb the nutrients from its victims' bodies over the course of a day or two like any sensible carnivore, the Sarlacc's body injected nutrients that deliberately kept the victim alive, not just for a few days, but for a thousand years. Granted you're in constant agony, but you're also strangely not going to die of old age while inside the Sarlacc. Whatever it's injecting into you must be incredibly good at halting the normal ageing process.

The Star Wars universe is a truly weird place to live.

[1] Canonically, according to the Expanded Universe stories, Fett later escapes from the Sarlacc, but that's (literally) another story.
