[Kirby] What happens to the living beings that Kirby swallows?

The little that I know is that Kirby inhales them, gets one of their powers, and can then spit it out as a bouncy star that disappears a few seconds later. But does anyone know what happens those he swallows? Do they get digested by acids? Is their life energy absorbed into Kirby's soul? Do they disappear into a parallel universe, which could explain why he can eat so much without being stuffed? Or is it just something completely different?

He eats them.

Because Kirby is a... pink... puff... Kirby-shaped... thing, he... Um... Let me start over.

Because Kirby is a whatever-he-is, he has an alien metabolism. He can almost-instantly convert anything he eats into energy with little to no waste. It's analogous to a mammal's digestive process, and whatever gets eaten is dead and can't be un-eaten. He can even do this to air, which is how he produces a strong vacuum force (by absorbing the air inside his mouth, which produces negative pressure). If he hasn't fully digested something, he can spit it back out whole. Once he has digested something he can only convert it into glowy star-shaped chunks of unstable matter.

This process is definitely *not* 100% efficient matter-to-energy conversion, otherwise there would be a massive explosion everytime he ate something. Kirby also seems to have very poor capacity for storing this energy, which is why he often loses absorbed powers when startled or injured, why he can't spit stars out whenever he wants to, and why he is always hungry.
