But the ball came back for Ogogo on the edge of the box and he rifled the ball into the far right corner on the half-volley.
First, Kaikai saw a low shot from the left well saved.
But just as the tie looked set for extra time, Ogogo popped up with the winner inside two minutes of the additional three at the end.
There was then another let-off for the Shrews from the resulting corner on the right as Gowling headed just wide of the left post unmarked from Townsend's cross.
Halstead had to make another smart stop with five minutes left when he latched onto Brown's misdirected header in the area on the right and struck fiercely first time to the near post with Halstead having to turn the ball behind.
Micky then opted for his final change with Black coming on for Barnett, but the chances were going Grimsby's way.
But Halstead's reflexes were superb and he turned the ball away one-handed to prevent a certain goal.
Grimsby's Craig Clay crossed from the left and Nathan Arnold looked certain to score as he sent a bullet header to the top right corner at the far post from inside the six-yard box.
But the biggest moment of the second half came when Shrewsbury goalkeeper Mark Halstead made a world-class save.
At the other end, with 64 minutes on the clock, Kaikai picked Junior Brown out in space on the left, just outside the box, and the full back stepped inside before shooting just wide of the right post with his weaker foot.
Bogle then found space in the Shrewsbury penalty on the right just past the hour mark, moved onto his right foot past Knight-Percival before blasting high into the side netting.
59 - Conor Townsend curled over a free-kick.
There was also a second injury problem for Micky's side in the second half as defender Whitbread was forced off with Knight-Percival his replacement.
And the first chance of the half fell for substitute Smith as he collected the ball just outside the penalty area on the right from Brown's cross and shot straight at the goalkeeper at the near post.
There were no changes for either side at the break as Shrewsbury got the second half underway, attacking the Salop Leisure Stand.
HALF-TIME: Shrewsbury Town 0-0 Grimsby Town

The striker then spurned an opening with a scuffed effort wide inside the boxx.
Two minutes before the break, Grimsby substitute Bogle turned on the edge of the box and fired a half-volley well over.
Shrewsbury were also forced into a first-half change and Jermaine Grandison looked to be injured, Dominic Smith was his replacement at right back.
But Paul Hurst's side should have taken the lead in the 25th minute when Conor Townsend crossed at mid-height from the left and Craig Clay controlled the ball around 15 yards out before turning and firing over the bar with his left foot.
The Mariners' Pittman was forced off with what looked to be a shoulder injury in the 23rd minute, Omar Bogle was his replacement.
And five minutes later, the ball fell kindly for Scott Vernon to shoot from 20 yards out, but his effort flew straight at the goalkeeper at mid-height.
In the 10th minute, Kaikai saw a free-kick from around 25 yards out fly well over the crossbar.
The Shrews made the slightly stronger start with Kaikai's early burst down the inside left halted, although Lawrence had to put in a block at the other end as Jon-Paul Pittman shot just inside the box.
