-Your Cosmo and your cooking with sprout (that's unfortunate for ya- <:D)-

You and Sprout were baking some Astro "cookies".. the problem is.. you were unaware what sprout put in the cookies when your back was turned to preheat the oven..when you turned your back..sprout was just happy and normal...but you noticed the black stuff in the cookie batter...but you shrugged it off...so you continued making these amazing "Astro cookies" with sprout

You/Cosmo: "Hey sprout- these cookies..smell funny...are you sure these are...safe?"

Sprout turned to you and smiled happily...not thinking much of it..which is weird- HMMMM-

Sprout: "eh it's probably nothing! It's probably Shrimpo exploding something on purpose" (jk)

You were not sure about it.. as you didn't hear a bomb go off... but Sprout was your friend...so you trusted him :)
