S2·E29 Jellyfish Jam

While sealing up volcanic vents in the ocean, First Squad is shrunken down to size by some Jellyfish and captured by the Zebra Brothers. Upon First Squad being brought to HighRoller, it is shown that the Jellyfish are actually tiny aquatic humanoids led by Yan Ching who have been tricked by HighRoller. When Yan Ching joins Big Green, he calls it "Little Green", to which Mighty Ray replies by correcting him, which he thinks doesn't matter. It is unknown how First Squad got back to their normal size.
