Valiant says “mee too!” and takes a dip in the hot spring. Folks who have a Smart Doll will know the rules about keeping one as it’s written on the included Care Card. The rules are
1:Never feed after midnight.
2:Do not expose to bright lights.
3:Do not get wet.
If you do want to expose them to water then you need the magic potion known as Ding which can only be obtained from Mr Wing but he will only exchange it for the Wand of Ming.
Some folks who do not have access to the Wand of Ming have figured out how to let a Smart Doll get wet without the potion though - they may share the secret with you in the comments. #smartdoll
