NerfRoblox Sharkbite: Web Launcher Rocker Blaster, Includes Code to Redeem Exclusive Virtual Item, 2 Rockets, Pump Action

Q: What ammo/rockets are compatible?

The only things I've had launch well out if it are Demolisher Rockets. I have the (teal-colored) rockets it came with, plus a bunch of 3rd-party ones. (I forget which brand/company.) They all seem to work about the same. There are probably some differences between the various 3rd-party brand rockets, but I don't know how major they are. The launcher will also shoot Mega XL darts, but not well. (Probably because the Mega XL darts have a loose fit on the launching post.)
