"Commander, it appears that fräulein Kalina is not around."
"We searched around the base for miss Kalina and we can't find her! Did she call in sick?"
"She's not answering her calls too and her communicator is not active."
"We did, however, found a strange cat in the data room. Don't know whose cat it is but it is cute!"
"Ooh! I wanna pet it! Bring it here!"
"I wonder where did miss Kalina go? I hope she's not trying to pull a prank today."
It's Kalina. In the form of a cat. For the 2020's April Fool gag. Dubbed Kalinya.
