"Yeah I won't be able to come in today. I woke up with a terrible stomach flu." You try to make yourself sound as convincing as possible but it's hard with the constant tapping of glass in the background, ushering you to cover the receiving end of the home phone as you whisper over your shoulder. "Shh, keep it down!" Before pressing the phone back on your ear.

"How bad? Like, really bad. I'm talking Niagara falls kind of bad-" you insist, successfully gaining a disgusted grunt from the other side of the line. "Sure, I'll take it easy and be back by Monday." You bid a few more farewells and hung up the call, sighing in relief for a brief second only to turn around and deal with your current predicament. A red bug the size of a small dog residing in a glass tank usually made for heavy live fish in restaurants, he's been slamming himself against the glass ever since Fionna brought him him an hour ago in the hopes of breaking free and running rampant.
"Nice try little guy but that's a reenforced tank," you knock on the glass to prove it's resilience. "Now, be a good bug and get cozy while Fi and the others figure out what to do with you. You cost me a week's worth of pay since I need to babysit you 24/7 so I hope you like the taste of cereal cause that's all I can afford right now." You remark at the little critter who can only return the glare you're giving him, pressing a halt to his endeavor against the tank and turned his back to you.

Atleast you two are on the same page now.

Just a few hours ago the only thing you had to worry about was buying groceries but before you knew it you got a text from your buddy Fionna who said she needed help taking care of some bugs, of course your first impression was that she was dealing with cockroaches but when you got to her apartment you were received by the sight of five or maybe six beetle like bugs the size of a five month infant. If that wasnt weird enough then you weren't prepared when those bugs unified and formed into a tall humanoid insect man hell-bent on destroying your friends, naturally you didn't want that to happen so when Marshall and Gary tackled the insect man and he dropped his crystal thingy you threw yourself to grab it before Scarab did, resulting in the four legged bug in the fish tank in the middle of your apartment. Who would've thought.
Fionna begged for you to watch over the bug guy while they try to contact some other guy to take him away, being that she trusts you more than Lsp considering what happened last time. You were already willing to shoot at a man to save your friend so what's some babysitting in comparison? 
And here you are, sitting back in your couch as you turn on the TV watching the news about city repairments after said bug man almost destroyed everything.

"For such a small fella you cause quite a scene." You muse out loud, hoping to get a reaction from the bug. "Well you sure don't look as menacing as you did a few hours ago." 

This annoyed Scarab, turning around to scratch at the glass with his front legs in your direction as his maw repeatedly open and closed as if to bite you. "Stuck a nerve huh?" You giggle at the little dude.
After teasing him a bit more you were left feeling peckish so you complied with your word and served yourself a plate of cereal. After the first few bites you felt a pair of eyes on you, or more specifically your plate. You poured a few cereal flakes for him  in a different bowl, opened the lip enough for your hand to slip inside but Scarab bit your hand when you were halfway into placing the bowl and ended up dropping it instead. "OUCH! You little-" you immediately retrieved your hand, shutting the lid closed as you rub your injured hand.
