*Boss's The boss pattern is dependent on how many frames have elapsed since the start of this room (so to clarify, this excludes stage 01 and stage 02). This means that by always holding right, and performing consistent actions, it's possible to always get the screensame pattern on the boss.*ClunkTo achieve this, get consistent got through the room taking special care to never let go of right, take the invincibility potion, and simply walk off the big ledge, taking a clunk. This will consistently lose exactly 18 frames, providing a good patternon the boss.*Once you're at the boss, position Simon on the middle step. Once the bat starts to move, move to the top step and wait.When the bat approaches you, there is a 1-frame window where you can whip and kill the boss in one hit. This is known as the [[Cv1/tricks#Critical_Hit_Glitch | Critical Hit Glitch]]*Crit*A general visual cue designed for people running on original console with a low display monitor (CRT or low delay LCD) in mind is depicted in this picture. This changes from person to person depending on reaction time and input delay, so experiment with your visual cue and try to create your own line a little earlier or later if you feel like it works better ('''Picture needed''').***If you fail the crit, there's an easy way to tell if you were late or early. If you were late, Simon will hit the boss for 2 bars of HP, and a red sparkle will appear around the bat, indicating a hit. If you were early, SImon will not hit the boss instead and it will stay at full health.*As a backup, activate the stopwatch and kill the bat there. You need to press either up+B on the same frame, or B 1 frame after pressing up, to avoid climbing the step (Can point '''gif''') === Simple Stopwatch kill ==={{#ev:youtube|QU1c3xGGcuQ|550}}*This is an easier alternative to the simple stopwatch Stopwatch killwith the Crit attempt listed above. This will require 10 hearts, append a gifgrab the big heart from the candle as shown in the video if you still need hearts.*Perform the same movements to manipulate the boss to swoop down, or just show but as soon as it in gets close to Simon, instead of attempting the video) ('''Add picture with visual cuesCrit, for this crit activate the stopwatch and fully climb the stairs. Then turn around and for start whipping down the bat. Activate the others''')Stopwatch a second time as soon as it runs out.
