This episode of Bluey is called 'Recruits'. Rusty's army roots started way back in his diaper days. His dad was in the army at that time too and would always tell his little trooper stories about his adventures. That left a huge impression on the little red kelpie tot and it even seeped into his playtime with his friends at daycare. Before he was Sergeant Rusty and training the likes of Private Jack, he was Private 1st Class Rusty. He would play army with his friends Mackenzie and Winton in the early days. Rusty would teach his friends about helicopters and army terminology. Mackenzie was great at running around following Rusty's commands. Winton was great at staying close to Winton and/or Rusty. He liked to stay rreeaallyy close to them for some reason.
