The oddest thing about squirbillus is that they swim around the sea of ahseed in odd numbers. If you come across a shoal and count them they’ll probably be three, five or seven of them but never two, four or six. Scientists were so perplexed they performed a number of experiments to try and find out why this phenomenon occurs. They cornered a group of three squirbillus, removed one and another turned up to see what was going on. They then isolated two in a tank and one of them immediately gave birth. In the end they had to conclude that the squirbillus are just odd creatures.
