Max Verstappen could not believe his eyes when he came 'face to face with Godzilla' during Practice Three at the Singapore GP.
The street circuit has seen its fair share of track intruders over the years, including a wandering pedestrian in 2015, but this was possibly an even rarer occurrence.
"There's a giant lizard on the track," exclaimed a laughing Verstappen as he passed Turn Three. "I am not joking."
"Face to face with Godzilla," says one of his Red Bull engineers.
It's suspected that the large reptile was a Monitor Lizard, a common species in Singapore.
