ender pearls & TNT can be loaded into regular crossbows

[potatoorsomething]

ender pearls and tnt are able to be loaded into unenchanted crossbows, and multiclip crossbows
loading a crossbow without pearling/cannoning consumes the pearl/tnt and will shoot a regular arrow (with multiclip 4 it consumes 5 pearl/tnt)

edit: if you load ender pearls into a cannoning crossbow (i presume this works the other way) it wont consume the pearl and will load a tnt for free
