So the kids meals will be getting Shovel Knight toys but the toys will also come with codes for in game DLC though it doesn't say what the DLC will be (betting cosmetics), however they only advertise Steam and Nintendo Switch so I guess if you have the game on another store or console you are out of luck.

Also plague Knight has been renamed to "Doctor Knight" so at least he is fully certified now.

Roast beef queen.

I thought there was nothing new under the sun, but apparently not. Shovel Knight is teaming up with Arby's is something I could have ever conceived before this moment.

Wow, this would be the only time i would ever willingly go into an Arby's...if I had one here.
The Arby's ads I saw when i was small didn't look good at all.
Also just realized it's called Arby's cause RB is roast beef.

Common misconception. It's for Raffel Brothers.

Oh that's kinda disappointing lol. But convenient for them i guess.
