The phrase “how old was Marbles” most likely refers to Mr. Marbles, the beloved dog of YouTuber Jenna Marbles (Jenna Mourey), who passed away in 2021.

Mr. Marbles’ Age at Passing

Mr. Marbles was born on June 5, 2010, and died on June 11, 2021.

A Beloved Internet Dog

Jenna and her partner Julien introduced Mr. Marbles (a Pomeranian) to their audience in 2010, and he quickly became a fan favorite in Jenna’s videos.

Over the years, fans celebrated his birthday every June 5, and the community often joked about “Mr. Marbles is dead” — a running gag that Jenna and Julien eventually retired as he aged.

Why the Confusion?

The name “Marbles” can also refer to:

• The toy (small glass or stone balls used in games), which have existed for thousands of years.

But in modern internet culture, especially in forums and YouTube communities, “Marbles” almost always means Jenna’s dog, Mr. Marbles.
