Mega bloks has two types of mini-figures. Ones for kids and ones for collectors. And these Turtles ones are clearly kid mini-figures. The kid ones don't have knees or elbows. But they do have ball jointed ankles (for Power Ranger high kicks I guess). Look at the mini-figures with current Hot Wheels sets. Exact same articulation pattern these turtles have (from the waist up anyway).
