Introduced by Johnny Morris With TERRY NUTKINS
You may start the day on an egg, but all birds start their lives in an egg. They break out from an amazing variety of shapes, sizes and colours, but why are they all so different? JOHNNY cracks the problem.
And TERRY discovers what life is like in an ordinary sea-side rock-pool, when he magics himself down to the size of a shrimp to go swimming with the crabs.
