She grabs the coins and the thing in the muck and skedaddles. 

Now she is back in the grassland, covered in blood, and being pursued by two spider-snake-eyeball-horrors, although they fall behind steadily as she flees.

She flees all the way to the river, where she can clean the blood off and examine her prizes more closely. 

There are two silver coins and three copper ones, and the copper ones are each a stack of ten. She can combine them all into a two-silver coin and a thirty-copper coin if she likes.

The other thing looks like... a little scrap of red meat, vaguely in the shape of a tattered heart, frozen into the same glassy immutability as all the other items she's encountered.

...Can she...do anything with it???

It has some crafting recipes! She could make... something... with {1/? Heart Piece}, and a few other things with blurred-out missing ingredients.

She captures some dewdrop slimes and takes them and her items and heads back to where she left Wilbur. 

The trip back offers her nothing more interesting than another apple tree.

She leaves the apple tree alone for the moment. 

Wilbur is surrounded by miscellaneous furniture items, some wooden tools, and what appears to be a suit of armor made of wood. 

She pauses for a moment to stare at this, then says, "Hey! I found a whole bunch of stuff. You should try one of these, they're good," she says, holding out a dewdrop slime. 

"...Thank you," he says, taking it very very carefully and biting into it. 

The bite is very tasty, in a sweet refreshing no-particular-flavour sort of way; the slime wriggles free of his grasp and baps him in the face, hard enough to hurt but not to cause lasting injury.

He grabs ahold of it, squeezing to make sure it doesn't wriggle free again. 

...Maybe squeezing a little too hard. 

SPLAT.

...

He wipes off of himself and eats as much of the thing as he can.

It's still tasty!

Good. Still. 

"Maybe I can work out how to make a container to kill those things into first," he muses. 

"Ooh, that's definitely a good idea. Anyway I found some stuff and I wanna ask the cute thing what the heck it is." She looks around for the cute thing. 

It waves from its perch atop a tree stump.

{what things?}

She holds up the weird heart thing. 

{is heart piece! can get more, make heart.}

"What's a heart?" 

{can eat heart!}

"Does anything happen if you eat a heart?"
