PikabooPikachu, Oh yes, trip to Japan right? Aren't you quite the cool person... Hope you had lots of fun. At grandparents house, no grandparents, no milk, and no food. Sounds awful! D: How long you going to be staying there?
Didn't really know that you were gone but at the same time I do recall realizing that you've been a bit less active recently. So errr, welcome back! Did you go anywhere or something like that? Or was it more just a break from Pokebeach?
PikabooPikachu, the best healing pin is called "Peace Full". It looks like a smiley face.
At full power you can use it 5 times and it heals 50% of your max HP while doing so. (There's also a pin with a pink flower design that can raise that to 75% or something, but I forgot the name.)
