Opal Pals is the second game in the High School in High School on the High School series.
The next year, Alica comes back to the high school. She and Linzea find out there is a rumor-spreading student in the school who has been telling the whole school that they are lovers. Alica and Linzea are mortified to find this out, and try and find out who is spreading the rumor.
Peira Noid, who is found out to be spreading the rumor, turns out only wanted to be Alica's friend. They become friends and the game ends.
This game is a point and click game. Clicking on various things will reveal things about them, and Alica can be moved with arrow keys.
