|Whittaker 13, Jerome 18, Johnson 54, 61, Hooper 69, 90||Venue: Carrow Road
MILLWALL were hit for six on a dark day at Carrow Road.
The Lions were 2-0 down at half time and collapsed completely in the second half as free-flowing Norwich ran riot.
The hosts were firmly in control at the break after goals from Stephen Whittaker and Cameron Jerome, and Bradley Johnson killed off slim hopes of a comeback with a third.
Johnson grabbed another in the 61st minute before Gary Hooper raced clear to make it 5-0.
Jermaine Easter pulled one back but Hooper completed the rout with his second and the Canaries' sixth in the final minute.
Millwall are now just three points above the relegation zone and face table-topping Bournemouth at The Den on Sunday.
Ian Holloway made five changes following the defeat to Bolton last time out.
Top scorer Lee Gregory was dropped to the bench, with Ricardo Fuller replacing him as the lone striker in a 4-2-3-1 formation.
John Marquis made his first Championship start of the season in an unorthodox right-wing role, while Mark Beevers returned after illness.
Matthew Briggs and Lee Martin also started but Scott Malone (hip) and Andy Wilkinson (back) had knocks, so missed out.
Norwich, who scored five goals in their previous home fixture, began with a swagger and the warning signs for Millwall were evident from the opening minutes.
It should have been 1-0 inside 90 seconds but, after Shittu and Briggs both misjudged a ball over the top, Jerome inexplicably sliced wide with just Forde to beat.
Hooper then had a goal disallowed after chesting in Whittaker's cross from an offside position.
The Canaries continued to pepper the Lions' goal, with Jerome's header and Nathan Redmond's bobbling drive both forcing Forde into action.
But the hosts broke the deadlock when Redmond played a pass inside to Whittaker, whose near-post shot squeezed through Forde's attempted block.
And when Forde's under-hit pass to Beevers was cut-out by Jerome, the forward rolled the ball into an empty net to make it 2-0.
Millwall were in disarray and an error from Briggs presented Jermone with another opportunity but he fluffed his lines when through on goal.
Marquis had the visitors' first noteworthy effort of the match in the 23rd minute, his deflected drive skimming the roof of the net on its way behind for a corner.
Normal service was quickly resumed however, and it took a goal-line clearance from Beevers to prevent Jerome's cross from finding a teammate at the back post.
Jonny Howson dragged the final chance of the half wide of Forde's post as Norwich threatened to further increase their advantage.
The Canaries continued to pour forward after the break and should have gone further ahead when Hooper exchanged passes with Johnson before stabbing wide.
But the same combination combined to score Norwich's third in the 54th minute, with Johnson thumping home Hooper's pass.
Johnson made it 4-0 when, with Millwall ball-watching, he was given the freedom of the penalty area to convert Redmond's unchallenged cross into the box.
Hooper finally got himself on the scoresheet with the fifth goal before Easter nodded into an empty net after Shaun Williams hit the bar.
But Hooper was free at the far post to round Forde and tap in the sixth to complete the scoring.
