Game de Hakken!! Tamagotchi 2 (ゲームで発見！！たまごっち2) is a Nintendo Game Boy game released on October 17, 1997 in Japan. It features ocean- and forest-dwelling Tamagotchi characters, both which would later be adapted to the Mori de Hakken! Tamagotch and Tamagotchi Ocean.
The game is separated into two modes: one where the player is in control of Mikachu, and the "Tamagotchi care" mode. When the player controls Mikachu, then can walk around a small village and look for items, visit other houses, and talk to Professor Banzo. Mikachu's house features a bug tank and fish tank, allowing the player two pets at a time, one of each type. Eggs ("Mori" and "Umi" types) can be found through searching the nearby bushes, trees and rivers. The "Tamagotchi care" segment is identical to that of the first Tamagotchi GameBoy game.
The game features 3 minigames:
- Guessing Game - There are 12 cells covered with sand. The player should guess under which one a heart is placed. There is also a cell with a skull in it which causes a loss of a point.
- Math Game - The player should help the Tamagotchi solve math exercises. There are 3 difficulties.
- Catching Game - The player should help the Tamagotchi catch boulders (on Umino) or flowers (on Morino). There are 3 difficulties.
FoodThere are 5 sorts of food for each Tamagotchi type. Each Tamagotchi has a food that he dislikes. For example, Mushibatchi dislikes leaves. There are 3 meals which fill hunger and 2 meals which fill happiness.
It is possible to change the clock speed by accessing the time settings. To access the time settings, Mikachu should walk towards the clock in her room. 3 time settings are available: fast, average or slow. The player may also move the clock forward when both Tamagotchis are sleeping.
Sometimes a boulder appears above the Tamagotchi's head. The player should immediately press the B button to tell the Tamagotchi to dodge it. If the player doesn't press the B button on time, the Tamagotchi gets hurt and should be healed by using medicine.
