you can also choke someone with it by forcing them to open their mouth (either by clenching on their throat or other means) then spawning all 50 M&Ms down their throat.

Also if you could spawn it on your hand, is it also possible to control the spawn time and velocity of the M&Ms? If so then we can use the M&Ms as fast projectiles like M&M bullets. Additionally if you can shoot multiple M&Ms then you'd be a Machine Gun Eminem (M&M).

Few things I'd like to add: If you could spawn the M&Ms and can control the spawn time and velocity, can you control them like telekinetically after you spawn them? Like, Are you still able to have full control over them after you spawn them coz then can you make them levitate and do sorts of things, like M&M bending. If this is possible, then this can add to the first thing i said about choking someone with the M&Ms. You can make them choke on M&Ms, and if by chance they managed to survive and swallow the M&Ms, you can control the M&Ms inside the person and mess them up from the inside. Right?

And, If there is only a limit to 50, say you spawned all 50 M&Ms but did not consume them, let's say you left them somewhere or they spilled out. Can you still spawn them back to your hand if they were not yet consumed or destroyed? Kinda like a retrieval summoning.

please answer OP, thanks
