If it were normal for Rumble to be blue, the package wouldn't need to point it out.
I don’t even know how this is up for debate.
God, yeah. A bunch of expensive exclusive toys and a backstory and a bunch of ludicrous club and ask-who-the-hug-ever fiction appearances/mentions to patchwork a bunch of jive that didn't need patchworking, even.
(You'd think at some point someone would've retconned this miscoloring of Rumble/Frenzy as some new guy and gave him a whole backstory and jive and Hasbro could use him as another recolor but no)
