It appears that the Hasbro team has no plans to complete Jabba’s band. We received Max Rebo and Droopy McCool in the ‘Jabba’s Sail Barge’ Cinema Scene, but it Sy Snootles is not on the radar anytime soon, as reported by SirStevesGuide in the Q&A:
SSG: Now that you’ve made Galactic Heroes figures of Max Rebo and Droopy McCool, there is a hole in the band. Why did Sy Snootles get left out of the set? Might Hasbro consider rounding out the original trio of palace band members by making a Sy Snootles Galactic Heroes figure? She would go great in a 2 pack with any of Jabba’s more prominent minions (Tessek, Ephant Mon, or Ree-Yees for instance) or perhaps Oola or cloak-wearing Luke. Seeing as these more obscure Galactic Heroes figures are fan-driven, if you were to make a Sy figure would it be based on her classic ”vintage” appearance?
Hasbro: We have no plans to make a Sy Snootles or some of the other figures. Galactic Heroes seems to be overwhelmingly kid-driven, and aside from a few 2-packs with relatively obscure characters later this year, we’ll be sticking to known and recognized characters going forward.
