Oranje were heading for the World Cup exit door having found themselves a goal behind with just two minutes of normal time remaining in Recife.
Following the game, the 30-year-old striker, who has missed four of his previous five spot kicks, told NIS: "I didn't have the balls to shoot through the middle. Arjen had the ball and asked 'Would you like to take it?'
"When I was there I thought about changing [my mind], as I had missed the last time. [But] what an adrenaline rush. This is the best drug out there."
The Netherlands will face either Costa Rica or Greece in the next round.
