Not sure if this was known but I stumbled upon this today. If Ed captures a kid who isn't your active kid and you're already on New Kid and press A and Start during the initial dialog, then press start during the screen transitions it gives you the New Kid command and you can just walk right out of the open door. It only seems to work for Ed (even works in his room, grab hammy, switch kids, let him catch you, do the thing, and you just teleported back to the first floor, right to the Silver Key basically which could end up being a nice time save since you can do everything I just mentioned with one kid.
Have at it folks:
I agree on the 2-Character% potential time save, definitely saved me a ton of time on Hamsteak%. Tried it for a while on 3 char Any% tonight, and it didn't go great, however I also feel like I wasn't playing super great tonight on Any%, too much ham on the brain.
I think it makes 2 kid steak's route the same as 3 kid steak. Duping the hamster is probably now slower. It didn't make sense to go out of the way to get the silver key in 2 kid steak but this puts the key right in your path and makes it more viable to get the jar and water.
