Those3 videos have got to be some of the most delusional things I've ever seen related to monitors.
And what is brekky???
First, on one video it appears you have a heating blanket on you to lure them to you.
In another, vid of "brekky", whatever that is, If that were one of my monitors, there would be no hesitation at all to grab that mouse out of your hands. First he looks like he's given up hope, just by the look on it, then it obviously was very hungry, smelled the mouse and came. I wouldn't concider that training at all, but instilling in the monitor that you = food. It's just relating you to food, or your hand to food. It just wants to eat and gets very narrow minded when it comes to that.
Try this. Place a basking light somewhere in the room away from you totally, set the temps up so they are adaquate basking temps, like 120-140. Place a couple mice under it, and you hold a couple mice, without a heating blanket, and see where they wonder to. I would bet 9 times out of 10 they go to the basking light, eat the mice, then stay under the light.
In another, the kisses video, which by the way, I mean, come on, that's just a joke. If I were to sit there with mice to attract the monitors, and started flapping my lips and blowing at them, they would also come to my mouth and investigate. Then probably bite me like it did to you. In a couple of years, please, if they are alive, take another vid of that now 4 ' savannah "kissing" you. I can bet it will be a bit different as it will have gotten sooo much faster reactions. Seriously, please be careful. I would't want to see anyone get mauled in the face by any monitor no matter how dumb they are.
See, monitors can seem to have an unbelievable sense of smell. I can be in a completely different room with mice, and my Salvadori smells them almost immediatly and I can hear it jumping at the doors of it's enclosure.
I didn't catch the bathing video if there is one, but why would you need to bathe them? If your enclosure, if you have one for them, provides adaquate humidity, there would be no need at all. Even then, instead of forcing them into the water, place a large water container in it so they can use it as they wish, not as you wish. If your enclosure it adaquate, I can guarantee they won't use it for anything but to deficate in or drink from. You won't catch them just hanging out in there if there isn't a reason or need to, and with a proper enclosure, there is no need to. If they "know it's bath time", I would say what they really know, is they are dehydrated and starting to die, so they seek out whatever source of moisture they can, and again, since I can bet your enclosure doesn't provide that, they again relate you to almost survival if nothing else. Kinda like, hey, I'm getting dehydrated, and since where I live doesn't provide that, I need to go to the next option.
I've been on here for years, and kept monitors for years, and I've seen many, many people try the things you are trying, and almost, if not all no longer have those monitors. Then they just disappear into the void, never to post again. I'm not talking a few, but many many keepers if they can even be called that.
To me, this forum is dedicated to monitor husbandry, and that doesnt' seem like any form of even close to monitor husbandry. More like monitor survival and not being to make any of it's own choices, just yours and when you want them.
I think you should read up on monitors and their natural behaviors, because none of those videos show anything close to a natural behavior. Just what you want.
Sorry to be blunt, but I gotts ta tell it like it is.
