It's a reference to the computer-based metric of time known as "ping", A.K.A. time required for a client computer to talk to a server and vice versa. Ping as a number is the milliseconds needed for a complete communication, and the term ping is basically used as a shorter way of saying "milliseconds" alongside the number, i.e. 300 ping equals 300 milliseconds of time needed for two computers to communicate.
Ping is especially-important and notable in regards to video games with multiplayer, since very fast computer-to-computer communications are needed for smooth multiplayer game experiences, where everything is properly-synced and everyone is seeing what's actually going on properly in real time. 300 milliseconds sounds like a tiny amount of time, and technically is to human perception, it's fucking ages for high-speed communications between computers, which means that things get fucked up by this significant delay.
The joke here is that, when a multiplayer game is laggy and has poor connection speed, the "ping" for a typical user is often something absurdly-high like 300 milliseconds, and all kinds of fucked-up shit happens with the visuals and player/object positioning due to this lag fucking with how the game shows and handles things. Things happening with a strange and random delay (i.e. hit someone, they react a few seconds later out of nowhere) is a common and frustrating symptom of high ping in a multiplayer game, and the way the apples explode out of the box with a visible delay after Bubbles punches it is reminiscent of that problem in games.
Short version: Bubbles punching the box and the apples flying out a few moments later out-of-sync looks a lot like how multiplayer video games glitch when internet connection speed is crappy.
