create implication cowbell (8054) -> bell (46417)
create implication cowbell_collar (449) -> bell_collar (22889)
create implication cowbell_collar (449) -> cowbell (8054)
Reason: Relatively self-explanatory BUR. A cowbell is a type of bell, and therefore a cowbell collar is a type of bell collar.
jingle_bell_collar already has these equivalent implications, so cowbell_collar should too.
