"ah... omicron, you have indeed returned," lambda muses, though they are far more curious about the giant blacephalon blaring light and music into their face, "and i see you've brought a friend."
"mm-hmm! this is... well, it doesn't actually have a name, but i've taken to calling it 'groovy long legs'! i found it dancing with a bunch of plantlike aliens on another planet," omicron explains excitedly before gently nudging the giant rotating disco ball. "go on 'n' say hi!"
the blacephalon does not speak. instead, record scratch-like sounds can be heard coming from it, and yet lambda somehow understands what it's saying.
"dance! We want to dance! omicron says you've travelled to many places. We would also like to travel. to dance with as many life forms as possible!" groovy long legs ekes out, its head spinning and bobbing up and down enthusiastically.
"i see. yes, i have plenty of data on different planets. i suppose i could use the company, if you do not mind me asking about you, as well," lambda proposes, which seems to please groovy long legs as a music hits a satisfying beat drop.
"yay, i knew you'd like them!" omicron cheers. "i'll stick around too, in case you visit earth again, hehe!"
"of course, you are always welcome to join, omicron," lambda floats over to give the porygon 2 a pat on their space helmet. "wherever you'd like to go, i will gladly lead you."
[omicron and groovy long legs are now askable/available to be sent out for asks!]
