Playing through Hamtaro Ham-Ham Heartbreak in Japanese, I noticed っち being attached to a number of words. One sentence example is 【オレっちのしょうばい？】
Another way it’s being used is with the Ham-Chat (the game’s made up hamster language), they turn こまる into the fake word こまっち。 So it’s obviously not proper grammar, but they’re using that pattern a lot replacing the る with っち。 So is っち supposed to just sound cute, or are they going for some other idea?

From [Tofugu](https://www.tofugu.com/japanese/japanese-first-person-pronouns/):
>俺っち

>〜っち has become a popular ender for nicknames recently because it adds affection and friendliness and sounds catchy (like “tamagocchi”). You’ll often hear 俺っち — a casual, laid-back form of おれ — because Jibanyan from Yokai Watch says it.

>In Shizuoka Prefecture, 俺っち is used as 俺達, the plural form of 俺.
There is also っぴ used in the same way.
