Oh he wants that cookie...
Can we talk about the fact the fact that the "one thing [Dennis] wanted more than anything else in the entire world" was not, in fact, the RPG. He doesn't care that there's no ammunition for it, or that he can't actually use it as-is, because what he really wanted was for someone to think of him on Valentines day. That was why he put the anthrax in the box. to stop the others from excluding him. Because even if they were being horrible to each other, he still wanted in on it.
For Dennis, the fact that he wasn't given gifts by the rest of the gang indicated that they didn't love him, and Mac giving him that RPG proved him wrong. He of course would never say it out loud, and still clearly works to suppress the full extent of his emotions even when he's just had an emotional outburst and is on the verge of tears, but Dennis craves this symbolic reassurance. Even as he actively pushes people away, shuts them out, pretends he's emotionless. He's upset that the others actually believe this mask of his, take it at face value and can't see past his lies. He wants to be seen and understood and he wants to be loved by his friends.
