I thought that the magical pies were supposed to add age onto the pets, but I've used about 4 of them now, and none of the pets I've used them on have gotten any older.

For example, these two boys are the same age. I've given one a pie and none to the other, but they are both still the same age: 14 days.

Am I mistaken about what pies do...or are they just not working...or what?

Thank you!
