Gloinky was a small alien child shown to about to celebrate his Blorfday (birthday) during one scene in Invader Zim: Enter the Florpus.
He was about to blow out the candles on the cake before Zim and Dib jumped on the tiny aliens' homeworld and ran on it, causing a hurricane that destroyed the celebration, causing panic and presumably killing everyone at the celebration.
Despite this chaos, Gloinky had a few bites of his cake before being dragged away by the wind.
This would imply that he and his family survived the Florpus and that at least a year has passed since his last party. Interestingly, he seems to be the only one getting caught in the loop, who will forever be having a happy time.
