Hull showed fight to avoid another fright and pick up a fifth Premier League draw in seven winless games.
It looked to be another horror show for the Tigers when Florentino’s first goal in English put Ipswich ahead.
With 13 defeats on Halloween they have the most of any side in history.
But Hull rose from a hellish start with a battling second-half display as goals from Tim Iroegbunam and Oli McBurnie – his second in successive games – put them in front.
Julio Enciso’s screamer, though, gave Gary O’Neil’s men a point their first-half efforts deserved.
Tigers keeper Konstantinos Tzolakis was lucky in the 16th minute when he was slow to clear in his box and got into a right muddle and just managed to nudge the ball away before Emersonn could take advantage.
And there was another reprieve for the hosts in the 34th minute when a corner caused problems and Enciso nodded in from close range, but the goal was ruled out for a foul just beforehand by Abdul Fatawu on McBurnie.
Summer signing Florentino – who left relegated after a permanent move following a season-long loan from – paid a chunk of his £16 million fee with his 22nd-minute strike.
Abdoul Ouattara picked out the Portuguese midfielder, who smashed his finish inside Konstantinos Tzolakis’ near post.
Hull failed to have a first-half shot on target for the third time this term.
But when they finally did in the 58th minute, midfielder Iroegbunam netted his own first Prem goal to level in fine style.
Boss Sergej Jakirovic had sacrificed centre-back John Egan for Matt Crooks to provide some muscle in midfield.
And the trick worked a treat as Town were finally tested and Iroegbunam collected a McBurnie pass into space on the right and was allowed to saunter forward without pressure and lash past visiting keeper Christian Walton.
That meant no clean sheet for Town again as their wait for a top-flight shutout extended to 28 games – since December 2024 at .
And they led ten minutes later when Florentino fouled Mohamed Belloumi and up stepped McBurnie, who struck against last weekend, to fire into the corner.
But a fine fourth goal of the game followed when Enciso scrapped 30 yards out and showed neat footwork before whipping a fabulous curling finish into the top corner.
Only a touch by a stretching Walton denied Brooke Norton-Cuffy as Hull almost snatched a first win since August.
