Green aliens and bunnies?

[Courtneyyjewell]

Was just hanging out with my gen 2, 4 year old. Went outside and 3 green aliens appeared! Then bunnies? It was super confusing but really awesome! Can anyone shed light to what I might have done to trigger it? Or was this just a normal event?

Which Tamagotchi version are you using? There are many. Since you mention that they're green, I'm going to guess that you're using the Tamagotchi On (the first colour model to be released in the West), and assuming that it's the Tamagotchi On, then your description matches the Eco-usatchi Triplets.

There's a bit more information on what they do here.
