Some software glitches are so weird and wonderful that everyone likes them and looks back upon them fondly.
There are two common breeding grounds of popular bugs. One is 8-bit and 16-bit consoles where the code, data and game state are stored in one homogeneous block, and a single misplaced pointer can read sound generation code as level data or write the graphic memory to the player inventory. The other is cutting-edge 3D games where half a dozen third-party renderers, physics engines and net codes can conflict with one another in freakish ways.
If a Good Bad Bug is liked

Ascended Glitch. Subtropes include
Minus World and
The Missingno..

Dead Character Walking.
Contrast
Game Breaker, as well as
Game Breaking Bugs that may not overlap with the former. They are
often helpful to Speedrunners.
This trope has nothing to do with friendly cockroaches and mosquitoes, or a certain cartoon rabbit.
