As the clock ticked down on deadline day, centre-back Willy Boly became Forest's 19th signing of a head-spinning close season, while Blackpool winger Josh Bowler - who was loaned to Greek side Olympiakos - and defender Loic Bade on loan from Rennes followed soon after.
Only four of the players that started Forest's promotion playoff final on May 29th started Wednesday's 6-0 hammering at Manchester City and that number will surely drop.
The former European champions, back in the top-flight for the first time since 1998-99, have spent close to £150 million basically constructing a new team. They also broke the Premier League record of most signings in a transfer window - 21.
The previous English record for the most signings in one transfer window was Crystal Palace's 17 in the summer of 2013, according to specialist website Transfermarkt.
Jesse Lingard, Morgan Gibbs-White and Renan Lodi were some of the more high-profile names to arrive at the club.
Forest's risky approach has been a curious sub-plot to a summer splurge of Premier League deals kick-started by champions Manchester City signing Erling Haaland from Borussia Dortmund for an initial £54 million.
Three months later it is fair to say the Norway striker has bounded through the transfer window like a marauding Viking, laying waste to defences up and down the country.
With nine goals in five league games he is already looking great value for City -- a club in the enviable position of slotting marquee signings into a squad oozing with quality.
For some of the other 19 Premier League clubs, the window has been fruitful but for others the complexities of the market kept them on tenterhooks until the window closed on September 1st.
While Forest's business looked like a manic supermarket sweep, Arsenal have been more selective.
Gabriel Jesus and Oleksandr Zinchenko - both jettisoned by Manchester City -- were snapped up early and have contributed to Arsenal's perfect start with Jesus, signed for £48 million, already with three goals and three assists to his name.
Tottenham Hotspur also got their main business done early with the likes of Brazil striker Richarlison (£52 million) joining from Everton and Ivan Perisic (free) coming from Inter Milan to beef up Antonio Conte's squad.
UNITED CRISIS
For Manchester United, the transfer window initially only heightened a sense of crisis consuming Old Trafford.
A fruitless pursuit of Frenkie de Jong, doubts over £50 million centre back signing Lisandro Martinez, Cristiano Ronaldo's uncertain future and successive defeats to start the season had new boss Erik ten Hag looking bemused.
But the window eventually provided some comfort with Casemiro arriving from Real Madrid for £63.5 million to beef up United's flimsy midfield and right winger Antony joining from Ajax Amsterdam for £85 million - a deadline day record.
However unpopular the Glazer family are as United's owners, they continue to bankroll their managers.
Chelsea have topped the spending list with United not far behind, but West Ham United's business epitomises the TV riches which give all Premier League clubs spending power that only the elite teams in Spain or Germany can dream of.
The Hammers have splashed out more than £150 million, breaking their transfer record to sign Brazil's Lucas Paqueta. Saudi-backed Newcastle United also flexed their financial muscle to sign Sweden forward Alexander Isak for a club record fee.
As ever, fans could be excused for scratching their heads at some of the movements.
Chelsea let Romelu Lukaku go on loan to Inter Milan, a year after paying Inter £85 million pounds for the Belgium striker, and also sold Germany's Timo Werner back to RB Leipzig for 20 million euros less than they paid for him.
Then the Blues ended the window with a mad scramble to sign another striker, with 33-year-old former Arsenal forward Pierre-Emerick Aubameyang arriving from Barcelona.
While Haaland's explosive start has instantly justified his fee, other big-name signings have made a different impact.
Darwin Nunez, Liverpool's standout purchase signed to fill the hole left by Sadio Mane, head-butted Crystal Palace's Joachim Andersen in his second game to earn a three-game ban.
One thing is for sure, the cost of living crisis facing millions of Britons has not infiltrated the Premier League.
Even before the deadline day frenzy, around £1.7 billion had been spent by the 20 top-flight clubs - smashing the record £1.43 billion of 2017 and more money than was spent in last season's two windows combined.
