This model was released in very early 1999 but didn't hit the stores for about a month or so (only websites had them) later. This one was collected February 6, 1999. Same as the regular ProYo II but in a butterfly configuration and new Crayon color. And just like the ProYo II, it is a take-apart design with a replaceable wooden axle. Side cap design is the same used on regular ProYo II.
While the card says ProYo II, the butterfly versions of this model were identified by Playmaxx with "GT" in the product name. Therefore, the more accurate name of this model is the ProYo II GT.
