How exactly do you control the forms of some wives? If in fact you can?

[Valerio80]

For the zombie wife you can freely switch from/to undead/human form simply saying your wife the formula you got doing the zombie miller's quest. To talk to your wife simply click on her portrait in hero screen.

For the frog wife it tournes into a frog after a certain amount of battles (if i'm not wrong after 13 battles the first time, and then once each 21 battles) and each time you can decide to keep her as a frog or to change her back to a lady by kissing her (talk with her and you can chose to kiss her).

I know this two only, maybe there are more that can change their form, dunno ^_^
