but is sometimes still very babyish. The Main Numberjacks Three (voiced by Alice Baker) - Three is pink, has blue eyes, busy, lively, and a bit “Me me me!” but is growing up. Slightly odd and eccentric, noisy, fun and full of herself. She is very keen to be seen as one of the bigger numbers – “I can do it!” – but she is not quite ready for it - yet. A wildly ambitious jumper, Three has a collection of "beautiful things" (which she keeps in a bright red box in the sofa's Cosy Room.) She does not go out on missions in the early episodes, but she graduates to properly doing so later. She is the principal operator of the Brain Gain machine in the sofa's Control Room. Four (voiced by Jonathan Beech) - Four is dark blue, has brown eyes, and a regular sort of number – nice, steady, and quite grown up. He is four-square, steady, logical and measured. Not hugely self-confident, he tries not to panic. “I’m not sure, but I’ll try a bit more.” Still happiest at home, not entirely happy as a jumper, but okay as long as things do not go wrong. Four is the mechanic of the Numberjacks, and enjoys fixing things. He likes trains and playing with the Bloop Ball in the Gym. He is the main screen operator and once gets an extra part of body. He looks up to Eight as a big brother and has a special bond with him Five (voiced by Laura Maasland) - Five is turquoise, has brown eyes, like Four, is definitely grown up, she is perceptive, sorts things out – quite cool, creative and artistic. She likes looking after the smaller numbers some of the time, especially number 2. Loves jumping, does it with grace and style, outgoing. “I’m fine!” She is a good and cool singer, has a good fashion sense (for someone who never wears clothes). In almost every episode, 5 speculates what else might go wrong, which we see as a 2D animation. Six - (voiced by Oliver Keogh) - Six is a yellow and “bigger” number, has blue eyes, like Three, enjoys playing tricks, and is good fun. Quite physical, he is a cool jumper, sometimes a bit too flash for his own good. He tends to be the leader of the Numberjacks, though perhaps not as bright
