Idea from "Old Starchy (aNickzz)"
Or maybe shaving should transform him into the Nice King for a day or two.

Taking off his crown for a while turns him into Simon?

I like that idea. Maybe wearing the crown transforms him into Ice King, and not wearing it returns him to Simon. But while as Simon, sanity drains quicker. The two could have different stats and meter caps, so maybe Ice King has low sanity that drains normally but Simon has higher sanity that drains faster?

phew.. ^^ it is easier to make a new "simon" mod XD

I have almost no idea how to make character mods but the coding would probably be similar to some other mods I've seen. There was one where you can play as a dragon and have different forms that do different things with different stats. There's another one like Woodie that turns into a werepig instead of a werebeaver.
Could probably ask one of those creators to copy the code and just tweak it for Ice King or if you make another mod. Your choice, of course. The base of Ice King right now is pretty cool by itself.

I can figure it out how to do, but it is not so easy as you think.
I started with modding since 4 or 5 days ^^

Oh I don't think it's easy. Just mean that you can ask some other mod creaters for their code and use it as a template for your own. Then you (shouldn't) need to do as much testing for bugs since their code is hopefully bug-free.

Yes but I must it implement to my code ^^

"and btw the text about elsa is not correctly spelled"

Pls, tell me whats wrong

@wyattarn2000
"and can you please give him custom lines"

He has costum lines. I added more time to time


@wyattarn2000
"and can you make his sound speech file him babbling like crash bandicoot"

maybe ^^

wyattarn2000
"oh i have an idea give him an ice one man band so it never breaks"

No, but good idea ^^


@wyattarn2000
"does he lose less sanity at bdawn/dark since hes a little insane"
o.O

You know, you might be able to accomplish a personality change with the crown by adding a tag to its LUA (like "owner:AddTag("simon")" or something), and then in his character LUA saying something like "if inst:HasTag("simon") then" apply these Simon stats to him, "else" apply these Ice King stats. I used a method just like this one in a mod I am currently working on for plain ol' Don't Starve, and it works fine for me.

@Mazziz
Thank you, one day I'll try it :D

maybe you should make it so yougurt chip makes his sanity go up

@carry for skins
Yougurt chip?

yah becuase ice king loves trail mix and his fav is yogurt covered chocolate chips

@carry for skins
I doesn't know that ^^ okay mabe one time
