Jack Jumps in

"Safety first, means you don't rush in where you don't belong!"

- Miss Jenny scolding Jack after his accident.

Jack Jumps In is the seventh episode of the sixth season.

Plot
Thomas was sent by Sir Topham Hatt to pick up a special from Jenny Packard. He arrives to see that his special was an eager front-loader named Jack to help the Pack clear ground for railway lines at the quarry. Thomas drops him off and Jack looks for someone to help. He asked Oliver the Exavator & Byron the Bulldozer. Eventually they didn't need help and Byron asks Jack to try Kelly the Crane. When Jack introduced himself, a lorry named Isobella tells him to mind her paint work, but apologizes and welcomes Jack after Kelly scolds her. They advise Jack to see the Foreman.

The Foreman introduced Jack to his bandsman & tells him to work with a small excavator called Alfie. Jack and Alfie were having fun until a dump truck named Max comes along and causes dust to fly over the machines. Jack could see that Thomas was right that he was trouble & Max was about to rush towards him, but stop just in time. Jack refused to move and tells Max to stop bullying. Max scowls and races away.

Later, Oliver is ordered to move a pile of rocks, but Jack foolishly tries to take some of them up a hill himself. His bandsman tries to stop him, but Jack was too eager too help, When he reaches his bucket up as he approaches the top of the hill, he loses his balance and rolls down sideways. Jack is upset and Miss Jenny is disappointed, but Isobella, Alfie and Thomas comfort him, which makes him feel better.
