Press Up, Down(2), Left, Right at the "Press Start" screen

Here's how you can get 99 sunflower seeds in a few seconds:

1. Go to the "Tip-Top Fair" festival.
2. go to the "Nail the rythm" stand.
3. just slam on the A button when there's a red one and on the B button when there comes a blue one so don't follow the rythm just slam on it like you are doing the "barbell lift" game! or when you fish on hamtaro RR!

P.S. IT WORKS!

Go to the area where Bo is standing next to the machine where you can play any Ham-Game that you have already beaten. Go to the Billboard closest to Bo's right and press A. Then, press L, A, L, B, A, B, R(2) to get the "Rainbow Riders" picture.

Go to Hamstarr Manor. Look behind Seed Pig-Out to find three hamsters sitting behind a table. Talk to the middle hamster one time, then press B, L, A, B, A, R to see the "Too Much Good Stuff" picture.

Press A to read the message on the blackboard in the Clubhouse. Then, press L, R, A, B.

Go behind the Hamster that you play the Hat game with and press A at the Shougon Wig. Then press L, A, B, L, R to get the "Does she know" picture.

To get one of the 3 hambini, go to the sparkle coast secret rainbow. Then find the guy who has a sailor's hat on. If you have Cappy, (the hampster wearing the green cap) then the hat will fly away. The hambini will now move to look at the "thing". After you pick up the hat, the (first grey) hambini will go to the brown hambini if you talk to it once more.

If you are in need of help in the turtle food case, I can help you a bit. the turtle food can be bought in the shop. you have to use the L and R buttons to scroll in the shop to find it, i think it is on page 5. then I had trouble finding the shop. you will need boss on your team, so that he can smash the rock that is covering the shop. it is (i think) 2 screens above the classroom. I need help on this part: i cannot figure out how to get the food to Inspector Hams! the hogging guy will get full once you buy the turtle food, but he will just stand there. does anybody know how to give it?

When you finish the game, wait for the unbearably long credits to pass. After that you can go to rainbowland from the ham-ham lawn, sunny peak, and sparkle coast! You can also go to secret areas from smaller rainbows. Invite 40 ham-hams to rainbowland and invite at least 20 to get to a special machine that lets you re-do any ham-ham game you like!

Go onto the ham-ham lawn. If he is there, talk to Jingle. He is the hampster with a guitar who looks like snoozer, the hampster who sleeps in a sock. He will give you a walnut. You can do it up to 10 times in a row. If you use a number of them, you can get more until you get to 10 walnuts again.

Help! There is no way to get the turtle food from that one hoggy ham-ham. If you want to get all 40 ham-hams for the rainbowland theater, you must help inspector hams solve the turtle food case first.
