Brock Purdy and his wife, Jenna, found a creative way to celebrate Halloween as they prepare to welcome baby No. 2. 

The San Francisco 49ers quarterback and his pregnant wife, who are currently expecting their second child, stepped out in adorable couples' costumes that put Jenna's growing baby bump on full display at the team's annual Halloween party on Monday, Oct. 26. 

The pair, who already share a 1-year-old daughter, Millie Joleen, dressed up as two characters from Disney's classic movie "Monsters, Inc." 

Brock, 26, was dressed in an oversized fuzzy blue and purple onesie as Sully, while Jenna dressed as his one-eyed green sidekick, Mike Wazowski. 

In several photos, the NFL WAG is seen proudly showing off her growing baby bump as she fully embraced her bright green costume alongside her quarterback husband.

Defensive end Romello Height dressed as Chucky from the popular horror movie franchise, while another Niners partygoer came dressed in a classic Michael Myers costume. 

The most unexpected fit of the night, and the one that seemed to draw the most attention, was a Daejon Love costume. You may recall Love was federally indicted after allegedly impersonating a 49ers player in a $1.3 million fraud scheme.
