Chuggington - Season 1 - Eps 49: Koko Takes Charge
When Irving leaves Koko in charge of the recycling yard, she's keen to show how responsible she is. In fact she's so excited, that she doesn't listen properly to his instructions. She ropes Wilson into helping her, and loves having an 'employee' to boss around. Because she hasn't listened, things go very wrong: machinery gets clogged with paper, the pallets get knocked over.
