Onomatopoeia is a fun word to say, but not to spell. When I typed it in Word, I was so off that they couldn't give me the correct spelling for it. I actually had to Google something like "word to describe a sound" in order to get the correct spelling.
The explanation I give in the second panel is 100% true. I actually made up Conus's answer on the spot.
The first panel was fun because I used my eraser to make the electricity. The second was kind of hard because I'm kind trying to find a chibi style that works. And the third panel? Lamest. Kamehameha. Ever.
