Raph is so caught in his angry little bubble he hardly pays attention to Mike's approaching footsteps until he's invading his space by trying to talk to him. It interrupts his furious train of thought like a rock pitched into the gears of a rusty machine, dissolving the mechanic drone of rage inside his head into a shrieking shudder-clanging.

"What!?" He snarls, wheeling around like he's seriously considering eviscerating him on the spot. How dare he interrupt the storm he's got brewing. How dare he even freakin' exist right now.
