In Raleigh, North Carolina, host Derrick Campana helps Kaitlyn surprise her sister Kamryn by creating a full-limb prosthetic for Kamryn's dog Amiri after he lost his leg in a golf cart accident.

Derrick travels to an animal sanctuary in Renton, Washington to build a brace for Amelia, a cow born with leg deformities. Derrick hopes that building Amelia a prosthetic leg will lengthen her life.
