The raccoon's other states. Walking is drawn and checked; climbing to the oven, hit or knocked over (the table at 0x53CE) shows up in ten of the dumps and is not drawn.
The cat (0x5088): how long it waits depending on the stage is known; it has not been drawn.
The variant at 0xE19A, which comes from the R register and the stage number (0x498A): how it is worked out is known, not everything it changes.
What makes one stage harder than the last —how long a shot lasts, how long the cat waits— is read from the code and not measured in the emulator.
