discord bots

i've made a server for my friends and i more tha na year ago. we call everyday, play videogames, put each other in jail...you know the drill. however, ive beenthinking about adding some bots.
here are some that i already have on my server:
-groovy
-mudae
-dank memer
-epic rpg

does anybody have a tip for a new bot to spice up one's server?
