(Mr and Mrs Grouper hiked along the path they stopped next to the guppies who we're waiting for them.)
Mrs Grouper: "Right let's hit the trail."
Mr Grouper: "Last one to the camping spot has to collect firewood."
All: "Wait up."
(They excitedly followed Mr and Mrs Grouper.)
Mr Grouper: "Alright kids be careful."
Mrs Grouper: "Okay kids slow down or you'll get tired."
