Season 1: Episode 7

Koko has her first big solo delivery job, picking up timber and delivering it to the paper mill - that is if Old Puffer Pete gets out of her way! In spite of Pete's admonition to 'take it slow and steady,' Koko speeds toward the timber yard, nearly ploughing into a family of squirrels! On her return she encounters the squirrels again - but this time she has to make an emergency stop.
