Three fights top the fear ladder: CatNap, Mommy Long Legs and Miss Delight
Asked:
“Poppy playtime boss fights by difficulty”
Difficulty here is subjective and sources disagree, so this is a sourced comparison, not an official rating. It draws on 29 captured rows: one detailed easy-to-hard ranking of 10 encounters through Chapter 4 (rank 1 = hardest; its #1 row was not captured, but several independent sources name CatNap as the top pick), plus 19 hardest-boss picks from other hosts, collapsed to 14 independent claims after removing syndicated copies.
Spoiler warning: names and encounter details through Chapter 5 follow.

The detailed list calls Mommy Long Legs its #2: an open chase made horrifying by taunts, cries and random arm stretches — hardcoregamer.com
Three independent sources put CatNap at the top, calling him "a patient nightmare stalking the entire facility" — macmyths.com
Chapter 5 is unsettled: one guide ranks Lilly Lovebraids as the chapter's hardest for "most mechanics + timing" — poppyplaytime4.org
Another all-chapters tier list names the Prototype (Experiment 1006) the hardest across Chapters 1–5 — a newer, source-dependent claim — dtgre.com
