Probably only available after completing the story. Buy the handgun.

Note from Jigglymier:

Best tip i have for the joke gun, is to beat the game and select Chapter 8 (Final Boss). When u get to the next level, you can pick 3 weapons and reroll em.

For most of these, it's best to complete the story for all the permanent upgrades, then get the rest from endless mode.
