Maybe I've been playing too much Phoenix Wright, but I noticed something contradictory about the Enchanted Springs.

The deion of the Springs states that "You come upon a spring surrounded by earth and surprisingly healthy looking plants. Even the local animals look very healthy and happy."

However, if your pet swims in the Springs, they always lose a portion of their remaining health.  The only time where they're healed is if they have a negative amount of health (in which case it actually says that they lose a negative amount of health) and even then it's not enough to bring the health into positive numbers; I don't think it's even brought up to 0.

Why then are the plants and animals so healthy if the Springs only take health away?

I suggest that a chance to heal your pet be added.  Not to be healed all the way, of course, just a percentage of either your removed health or you total health (probably the former so that healing works the similarly to hurting).  Besides, it can either give or take TU, so why not health as well?

Also, the Scria Care Center is down at the moment, so I suppose the Springs healing could be like a bit of a backup care center.  But since you can only use the Springs once per day and the chance if healing would be fairly low (and you couldn't get a full heal unless you were close to full health anyway) it wouldn't replace the Care Center altogether.
