If we can suggest anything, how about ear penetration/brainfucking?

Honestly, this game isn't enjoyable. Slingshot upgrades being temporary really sucks the fun out of the game because upgrading anything never gives a net positive gain. You're better off not upgrading anything, and that just makes it not fun, as you won't ever get far, whether you get upgrades on that run or not.
Idea 1: "Fire" or "Hire" the duck, with job-related responses
Idea 2: "Launch" the duck, with a spaceship related response
Idea 3: "Record" the duck, with a response about recording the duck swimming in the water.
Idea 4: "Draw" the duck, where you draw the duck with a paper and pencil. The duck ruins the paper by getting it wet.
Idea 5: "Trick" the duck, where you do a bad magic trick. It doesn't work.
Idea 6: "Run" the duck, changing the duck sprite to a pixellated one with a joke about old computers (maybe?)
Idea 7: "Meme" the duck. A line about posting a meme about the duck to Reddit (or a name similar to it but duck related)
Idea 8: "Zap" the duck, with a line about a laser gun.
That's all the ideas I can think of, hopefully it helps you with adding more words!
