The King Boom Boo fight's probably the best Halloween thing related to Sonic this year and it's coming from Gamefam, not SEGA.
I have a feeling they intended a King Boom Boo boss fight since Pumpkin Panic event in 2022.
I remember playing the Halloween event for the first time and when I finally had access to the castle, thought it was weird it had such a wide courtyard, as in a place for a boss battle. Instead of was more stationary boo ghosts for me to attack.

I can tell they went hard for Halloween that year, but could also tell they couldn't finish it all on time. Even some of Pumpkin Hill looked unfinished.

I haven't played Sonic Speed Sim in ages, so I dunno if they fixed these yet.
A strangely familiar face arrives to Sonic Rumble Party!
