All of Bluey's friends from around the neighborhood just graduated from Middle School. It's Late August as they're getting ready for High School, more commonly said by the kids, 'Big Kid School.' Bluey is curious, yet terrified. Rusty is ready, yet confused. Indy is nervous. Mackenzie is ready to take it on. Jack knows it won't end well. Lucky is prepared. Honey just wants to read a book. Coco is impatient. Snickers wants to be the top in science class. Chloe will stick with Bluey for it all. Judo is ready to finally become popular. The terriers have each other's back. Then there's the kids from other schools. Two in particular are very special... Chestnut Canaan, the Canaan dog. He's just moved to Australia from Israel. He looks like an over-protective golden retriever. Milkyway Karelian, who's just moved from Finland. She seems to have border collie in her blood.
