A wild OVA appears!
Kanamori accidentally designs the Kiwi while trying to make the last bird-like bird possible.
The team get an impossible request:a creature that doesn't sink, is immune to extremes of heat an cold, requires very little water, and can stand on painful ground.
Each of them take a separate requirement and build their own creature to fulfill it.
Tsuchiya opts out: because, as they say, the Camel is a Horse that was designed by committee.
