Your idiot friend; Chance Sureshot decided to pay for lunch while you all were eating at the space station, but he forgot his wallet, so he's not allowed to leave since the waiter robot put him in a forcefield. He said he left his wallet on Mantis Planet when he was partying there, so you, Mordecai, Rigby, the robot, and the space gal went to Mantis Planet to find it. When you went there, you greet with some mantis guards who seem pretty nice. The mantis guards sent you to the king and he is pretty nice too. You and the gang ask the king if they can take the wallet back and he said sure if they stay for a feast. You fellas don't care and go eat dinner with them and they cut to dinner. You and the gang is excited to eat, but the food that is served is disgusting, so you pretend to eat it except for Mordecai and Rigby. You finish the feast and then cut to desert. You don't wanted to eat it so you gave the plate entirely to the Mantis Princess... She starts to cry and she says:

Princess: "YES, YES, I will marry you!"

Turns out giving someone your food in the mantis planet means confesding to them, and you didn't know that, so you're stuck here with the gang.

King: "Ohh, you sneaky little bastard! That was your whole intention , huh? 'Taking a wallet back'! Hahahahahah!"

The king said while laughing from the joy of finally his daughter getting 'married'.

Rigby: "Wait, hold on what the frick is going on right now?"
