Thomas & Friends Minis

Fizz 'n' Go Percy & Puppy Set (includes: Fizz 'n' Go Percy, Yellow Cargo Car, Blue Bath Bomb and Mini Unicorn Animal) All Thomas & Friends Minis have a Year/Wave label on the front of the Blind bag and a code on the reverse. The last numbers on the code will tell you which engine is in the bag. So 2018/4 with code number 145 is Gordon. 2020 Wave 1 (2020/1) 113 Light Up Rosie was originally going to be made in her original livery, but the final product features her in her current one.

The range was first produced in Thailand having weights inside. Some 2016/4 models continuing into 2017, the production moved to China onwards, removing the weights. The overall design and make have relatively stayed the same.Spring Basket (includes: Sweets Sidney, Sweets Ferdinand, Bunny Rosie, Easter Emily, Exclusive Thomas, Exclusive Toby, Exclusive Emily, Exclusive Scruff, Exclusive Charlie and Exclusive Harold) New Look Emily is the first piece of merchandise that depicts Emily with her number 12, which she gained in the twenty-fourth series episode, Emily to the Rescue. Steamies Rule! (includes: Classic Thomas, Classic Gordon, Classic James, Classic Percy, Classic Emily, Classic Nia, and Classic Rebecca) Belle's prototype models are exactly the same as Rosie's, and she has handrails on her roof for her 2019 re-release. The only exceptions for the former case are the prototypes of her Light-Ups and Monster variants. Classic Charlie is missing his brass fittings on the side of his smokebox, this was fixed on his Robo variant, but not on any other variant.

was the third year for the Minis range and Mattel released brand new Minis themes including: Steel, Construction, Aquatic, Night Time, Space, Monster and Animals, as well as new characters incorporated into the Classics theme. It was also the second year for the Tootsie theme (exclusive only to the US/Canada), as new additions were also announced. A new crossover theme was also announced for 2017, that being the Mighty Morphin' Power Rangers and Teenage Mutant Ninja Turtles. For the first time, road vehicles were added to the range. Classic Bash and Classic Dash and their variants ( excluding Sports Bash and Creature Dash) had flat wheels.From the release of 2016/4, the Minis production facility has been moved from Thailand to China. Coincidentally this wave also had re-used numerical codes that were also seen from other waves in 2016. They also had gaps in between chronological sequence. This is the first wave that this has occurred.
