Despicable Me 3 (2017)

Plot hole: After the car is destroyed, Gru is knocked unconscious and Dru enters Balthazar Bratt's robot to destroy the robot's core from the inside. Once Gru wakes up, Balthazar attempts to kill him with the robot's laser and Dru destroys the core causing the robot to collapse. Gru then yells out "Dru!" and runs over to the wreckage of the robot to try and find him. The problem with this is that since Gru was knocked unconscious before Dru entered the robot, and Gru knew nothing of Dru's plan to disable the robot's core, there is no way for him to know that Dru was inside the robot.

Casual Person

Lucy Wilde: Agents Grucy are closing fast!
Gru: Yes! Wait, whaa? What did you call us?
Lucy Wilde: Grucy. You know, Gru and Lucy mushed together - Grucy.
Gru: I like it, but not a lot. I don't like it.

Trivia: When the beach-goers panic on seeing the appearance of Balthazar Bratt's robot, you can hear the Wilhelm scream.

Question: Between the first two films Gru had hundreds of minions but in this film he's barely got a handful left. What happened to the rest of them?
