I just checked the Walkthrough for this. When helping with homework you can give a massage. When that happens look on the desk near the lamp. I'm pretty sure that's where I found the Cookie. According to the guide this happens on THURSDAY, so be sure you have the right game day. If this doesn't work try another day, but I'm pretty sure I followed the guide to get this.Ok I managed too find Alice's first cookie. But i'm still stuck on Lisa's... The walkthrough says "on a book near a lamp, if Lisa is dressed in pink casual clothes". I have repeated this scene almost 10 times and this is the only time the book gets shown during the hand massage, but there's still no cookie to be found? Is it possible that my game is bugged?
That's what I remember, but I could be wrong. The only other thing I can think MIGHT be an issue is Lisa's MOOD, make sure it's as high as possible.
Hope that helps
