Implicating old_toon → toony
Link to implication
Reason:
Old toon seems to be a descriptive tag for a specific kind of toony style (aka the "rubberhose" or "fleischer-esque" style in vintage funny animal animation such as Felix the cat, old Mickey Mouse, Betty boop, etc).
Since it in itself is a highly iconic toony style, I don't see why it shouldn't imply toony, as it is a specific type of toony.
