I ran out of ideas after messing around with the bee, villager and Ender dragon then I made ice Slime. Say hello to Ice Slime.

I feel as if the slimes are too rare in minecraft now, i've make at least 16 different survival worlds an maybe 30 worlds in total since the 1.16 update and haven't seen a single slime yet, no matter how many swamps i pass. Whats with that?
