A toddler and his grandfather appear to be spreading smiles on social media after their bond was shared in a mashup video garnering nearly one million views on TikTok.

The grandfather, lovingly known as "Bop," has a close relationship with his 2-year-old grandson, Brooks Vanhoy. 

Brooks' mom, Shelby Vanhoy, told Fox News Digital via email that she and her family moved to North Carolina from New York City to be closer to family — and her son's tie to her father, Mike Vanhoy, grew immensely.

"Bop is retired, and he’s been coming over every Thursday morning for ‘Bop Day’ since we moved back to North Carolina," she said. 

She added, "As soon as Brooks spots Bop's truck through the front door, he jumps up and down with joy, yelling, 'Bop's here!'"

Vanhoy said her father got the nickname "Bop" after she tried teaching Brooks how to say "Pop."

"Bop is what stuck, and it’ll probably stay Bop forever now," she added.
