My friends are running a Russian Invader Zim Ask on VK.com, and I’m replying there as ZIM. I credted this pic as an answer to a general question.
Despite being a jerk, Zim does love his lil' cute children. <3
The smeets are Siegfriend (Zig/Zik for short; has dark ruby eyes), Victoria (Vik/Vika for short; has pink eyes) and Nicolette (Nik/Nika for short; has blue eyes). The all are dressed into vigoriens' smeet suits.
