The Cow and The Calf

OBJECT:
Use the 8 pieces to construct a 4x4x4 cube (the COW) at this stage the Cow is a virgin. (there are 2 ways to achieve this)
Disassemble the COW. Choose 7 of the eight pieces add the 2x2x2 cube (the CALF) then try to construct the COW with the CALF enclosed within it. The Cow will then be pregnant. (there is only one way that the Cow can be made pregnant!)
In order to give birth the COW has to be constructed again using the 8 pieces; but you must find the the second solution.
This an improved version of the original Cow & Calf (TW13)
