...I got this idea while rewatching the movie.
I noticed Sandy guzzling down eggnog in one scene so I wrote this.
...Why no, I'm not questioning my sanity, why do you ask?
'How could you Sandy?! Thanks to you, there'll be no Easter!'
A couple days before…
'Cookies? Eggnog, anyone?'
Although it was an ope invitation, Sandy was the only one to partake in the offer. Bunnymund was too busy arguing the importance of Easter so why not wait until the topic of their gathering came up?
A yeti approached holding a tray of eggnog, cups arranged neatly and brimming with said beverage. Sandy had never tried it before but how bad could it be? He took a cup and got a whiff of the creamy scent.
Smelled promising.
He then took a delicate sip. Then another. Then began to guzzle the thing down like oxygen. On cup after the next was constant eggnog-y goodness. After downing about six he finally stopped himself.
What was it that made the drink so delicious? There was egg- Egg.
Sandy's eyes darted over to the egg Bunnymund was painting. It was a boiled egg, right? Maybe if he could try it he could get to the bottom of eggnog's mysterious addictive flavour…
No. He mustn't. For whatever reason Sandy felt like it would be a trap into a vicious cycle that wouldn't stop until the destruction of those he cared about and then himself. Something about eggs was-
Now the egg was in his hand and he was cracking open the hand painted shell. Bunnymund seemed to not have even noticed so engrossed he was in debating the importance of his holiday over North's.
He looked down at the perfect white shape sitting in his palm. It was so smooth and egg shaped! Curiously, he broke the egg in two, watching how the rubbery whites separated to reveal the creamy yolk inside. To think that what he was holding in his hands could have become a living thing. Any egg could!
Sandy almost felt bad for the egg. Almost. In one smooth motion he gobbled down the egg just as he realised the moon was trying to to tell the Guardians something.
He needed more.
All the running around made Sandy have a desperate craving for more. Those spotlessly white and yellow filled eggs. Whatever their form, he need more. Sandy knew Bunnymund had tons of eggs. If he could get his hands on those…
!
That sneaky Pitch! While he was distracted thinking about eggs he went and fired an arrow of nightmare sand at him! Sandy felt himself getting weaker but the eggs! He needed those eggs… Maybe if he took the opportunity to disappear to Bunnymund's warren…
He heard Jack scream but Sandy knew he'd be alright. He'd rejoin the Guardians as soon as he could! He just needed more eggs.
Present day…
'How could you Sandy?! Thanks to you, there'll be no Easter!'
Bunnymund raged about his warren, glaring at the heap of broken egg shells. North and Tooth looked confused as could be, most likely wondering why it was that Sandy was alive and viciously devouring Bunny's googies no doubt. Jack, however, seemed content to make snide remarks to himself about how they thought Pitch and his nightmares were the worst of their problems. At the top of it all was Sandy, finally at peace with his egg cravings.
A sort of inner peace and clarity settled over him, finally understanding why it was that the Pooka was so enamoured with eggs. But no more! Sandy had fed his cravings to the fullest and was egged out. Now he and the other Guardians could focus on beating Pitch.
...Well. Another cup of eggnog couldn't hurt.
