I created this pattern for my friend Sam after we watched Infinity Train together! One-one is one of the show’s most iconic characters and I love his gimmick of splitting into two. This pattern makes one each of Sad One and Glad One along with an outer case to hold them, resembling the fully round One-One. To put the whole thing together, put the smaller Ones together with their legs interlocking, and place them inside the outer section which has a button closure.

This example was made with Red Heart yarn size 4, and measures: (3.5 in/9 cm diameter, 2.5 in/6.5 cm tall) for the small Ones, and (5.5 in/14 cm diameter, 6.25 in/16 cm tall) for the larger One-One.
