Middle phase answers: "Misbehaving child" = BRAT; "Programs that might be used to chat" = BOTS; "Vessel with life vests" = BOAT; "Large, slithery hunters that constrict their prey" = BOAS; "Phooey!" = DRAT.
Ordering phase: the valid middle chain is DRAT → BRAT → BOAT → BOAS → BOTS. This permutation is the only valid one-letter chain for these answers.
Transition 1: W→T at the fourth letter (DRAW → DRAT).
Transition 2: D→B at the first letter (DRAT → BRAT).
Transition 3: R→O at the second letter (BRAT → BOAT).
Transition 4: T→S at the fourth letter (BOAT → BOAS).
Transition 5: A→T at the third letter (BOAS → BOTS).
Transition 6: B→L at the first letter (BOTS → LOTS).
