@shinymetal,
#3 wouldn't be bullseye, but Faerie Bubbles. Look at the main image. Not the proper word, but it still matches the description.
#4 woudn't be the Avatar collector, since it's a yellow star, not orange.
I also noticed the fragments have the following number of letters each:
32
30
28
31
and the fragment missing the word has 28 letters in it.
Of course that seems silly since it's suggesting that it's a 1 letter word!
maybe someone else can see a different pattern!
also note:
32 -2=
30-2=
28+3=
31 so maybe +3=
34? that gives you a six letter word.

Tuna- also spells "a nut" (which it can't be) and "aunt"
also why not combine the tuskaniny and leek theroies and throw an "s" into the mix for the scramble: anuts
Just throwing out my food for thought
