i'm MEGA late but yes happy birthday to them. i'm sure they had a grand banquet and meta knight somehow ended up drinking too much and had to leave early.

YAY YAY YAY!

King Dedede would definitely throw himself a huge exorbitant, indulgent, extravagant birthday extravaganza. Everyone and anyone would be allowed to attend. Provided, of course, they bring his royal majesty a gift! I think Kirby and King Dedede would spend their birthdays eating cake and partying!

cake eating contest. kirby wins everytime.
