I just discovered something I'd never noticed before in Thousand Year Door

This might be common knowledge for some of you but I was unaware of this until today and thought I might share it with some of you. You know how Lucky Start can make Mario electrified, dodgy or gradually recover HP and FP for three turns in the beggining of a battle? Well apparently, if you have a Feeling Fine badge activated it prevents you from being electrified, despite the description only stating that it makes Mario immune to Poison and Dizziness; this makes Volt Shrooms useless since their effect is negated and also prevents you from being electrified by the Lucky Start badge, meaning that if you have both equiped there's a 25% chance of Mario not getting anything from Lucky Start when he enters a fight (the word "Lucky" will still appear when you enter the fight but it won't have any effect). The only way for you to be electrified while still having Feeling Fine activated is if you equip a Zap Tap Badge, as it is immune to the effects of Feeling Fine. I didn't know this for the longest time and it actually seems like a it's a detriment for Feeling Fine to have this side effect. Is there any advantage for Feeling Fine to prevent you from being electrified? Maybe I'm missing something
