we need lore for how ice cube gets frozen and cubed again every time

I feel like it's obvious; he just gets reincarnated in the freezer.

How does he get there

The faucet pours a new "body" of water into the ice cube tray for him to get reincarnated in. Then the tray gets put into the freezer for the reincarnation to happen.

I think this comic implies it: imgflip.com/i/9xu2bj

Maybe the lore isnt that deep, or it's just a different cube in every comic 🥲
