‘Hey, Jake,’ Finn, a teenaged boy, called out to his friend Jake, a dog, as they walked through the Land of Ooo. ‘You ever wonder what a demon’s heart looks like?’

‘Of course, dude,’ Jake answered.

‘You ever wonder what a demon’s heart tastes like?’ Finn asked. Before Jake could answer, a skeleton in a black cloak blocked their path.

‘Hey, kid,’ the creepy thing cooed. ‘You want some magic powers? Magic powers for absolutely free?’

Finn replied without a thought.

‘Wait!’ Jake cautioned his friend. ‘Let’s not be too rash. Just look at this guy. Check out the sunken, lifeless eyes, the foul stench of decay.You know what that means?’

‘It means he’s evil, I guess,’ Finn shrugged.

‘Well, evil, sure,’ Jake agreed. ‘But mostly, he’s unattractive. And unattractive people are desperate.You should haggle with him.’ Finn nodded. His friend was on to something here.

‘Hey!’ Finn yelled out to the creepy creature. ‘I want more than just free powers. What else you got?’

‘Oh, all right,’ the Grim Reaper sighed. ‘Free powers and…’

The Reaper broke off one skeletal hand and quickly made a novelty item out of it.

‘…and this keychain,’ the Reaper continued, rolling his eyes.

Finn yelled back, jumping up and down. This was awesome! He’d haggled and, for his trouble, been rewarded with a free keychain!

‘Play it cool, Finn,’ Jake cautioned.

‘Right,’ Finn answered, toning down his excitement before turning back to the Reaper. ‘I begrudgingly accept your offer.’

‘Yes!’ the Reaper replied gleefully, laughing as a bolt of lightning shot down from the sky. ‘Then the deal is struck!’

Suddenly, an egg-shaped pod made of monster eyes and teeth appeared in front of them. It was surrounded by flames and smoke. A short staircase led to its entrance.

‘You can pick up your powers right through that door,’ the Reaper said casually. Then the strange creature – missing one bony hand – click-clacked away.

Finn and Jake looked at each other with you-go-first expressions before going through the door together.
