Eloisa is a Shakespearean scholar; did you know that she is a pun theorist – that is, a scholar who specializes in puns? Naturally, this means that she's a veritable treasure trove of bawdy puns. Here's a great riddle from the 1600s:

It is a Penne with a hole in the top,
To write between her two-leaved book;
It is a thing both dumb and blind,
Yet narrow holes in dark can find.

Did you figure it out? Need another clue?

It is a dwarf in height and length
And yet a Giant in his strength;
It is a bachelor's button, newly cut:
The finest new tobacco pipe!

This is Eloisa's Egg #25 - "collect" them all!
