Yeah Kinda feel strange after Smoothie,Daifuku,Perospero and EVEN Compote get screentime with defending the ship. Either they don't really know it and Oda show later that Snack wasn't their or we see him in manga too later.

So it seems like Snack is with the troup, but I can´t see Oven,Cracker or Katakuri.
I think all three stay behind, which means two sweet commanders+veteran protect the homeplace and Big mom take another two sweet commanders and three veterans with her.
