Of course it would, but wouldn't you think they would do some research on characters while developing the game to not make it so bland? In fact, considering they have Ninji of all enemies in Sticker Star, it's at least possible they did some.
Ninjis were in SMB2, one of the more well known Mario titles. It's actually not that improbable that they were in the game.
And yeah they did do some research obviously. They looked at SMB1 2 3 World, Captain Toad, Mario Kart and the NSMB series. Basically the franchise's earliest days, or something really recent.
To be honest I wouldn't be surprised if they've never even heard of things that appeared in sunshine that hasn't continuously stuck around so stuff like petey piranha or gooper blooper they could have easily seen in more recent Marios due to their continued reappearances.
I mean it's not like that game has ever been available in any significant capacity since it's release over a decade ago.
