Debirutch no Tamagotch, also known as the Devilgotchi is a Tamagotchi release which debuted in Japan in early September 1998. The Devilgotchi’s official English release was in the form of the mobile game Tamagotchi Monster in 2006.
On the Tamagotchi Planet lives a special race of bug-like Tamagotchi characters called Mushitchi. While Mushitchi can be found all over the planet, their biggest and safest home is the Mushitchi Forest. Mushitchi hide amongst the leaves, grass, dirt, and under the ground. Due to this, other Tamagotchi wandering in the forest accidentally step on them occasionally. On the Morino Tamagotchi, the user is tasked with caring for a Mushitchi, helping it grow big while avoiding getting injured.
The Tamagotchi Ocean is an ocean life-themed Tamagotchi released in Japan in March 1998 and later on in the USA in August. The Tamagotchi featured a motion sensor, similar to the Tamagotchi Angel, which was used to scare underwater predators away.
Pokémon Pikachu, also known as Pocket Pikachu in Japan, is a limited series of two portable Pokémon digital pets (similar to Tamagotchi) featuring the famous yellow electric-type Pokémon, Pikachu. Released on March 27, 1998, in Japan (November 2, 1998, in North America).
According to Mikachu's logs, gendered Tamagotchi characters were a new discovery made while the Tamagotchis were living on Earth, and had not previously existed on the Tamagotchi Planet. According to her, the Osutchi and Mesutchi characters starting being born when couples began sharing their Tamagotchi pets with each other. As Professor Banzo often get flustered about the concept of love, Mikachu spearheaded the research on them. Since the original "Tamagotchi HOUSE" model was inadequate for caring for a growing Tamagotchi family, Banzo and Mikachu together developed the "Osutchi HOUSE" and "Mesutchi HOUSE"
