Angry vibes

Even a mellow fellow like Doodle can lose his temper. However, he doesn't just lose his temper like a normal person would. Instead, it bubbles up inside him until a Teapot can be heard, until he finally snaps, ripping his ribbon mouth open and speaking in loud, inaudible banter, often sounding near demonic. However, even when he gets THIS mad, Diana can slap him back into his senses,  often thanking her for her brutal smacks. 

Doodle's angry look in both this and the previous image with Nickel were inspired by this small segment from the online short "Double King": youtu.be/w_MSFkZHNi4?t=531

Why is he mad? Who the hell knows? Doodle can only put up with so much, ya know?
