Join these cute baby cells as they work hard within their tiny body! A mini-Red Blood Cell picks up oxygen from the helpful ladies at the Placenta, and meets a White Blood Cell for the first time, in this adorable spinoff of Cells at Work! But when tremors begin to shake their world, they'll need to consult the Gene Library to find out what's going on! Could this be...a contraction? And might their body soon have to...fend for itself?!
