YAY JEFF

dat freakin scout, from team fortress 2.

^ added to the list

you have a tobuscus easter egg so why not a pewdiepie one

@barberac I'm not as familiar with him... I have some questions before I add him:
1: Is he still popular? (At least as much as tobuscus is now?)
2: Does he have any particularly popular sayings or events?
I'll research these on my own but if you know them already it would really help :)

Edit: I found #1 on my own.... Although tobuscus has videos with just as many/more views, pewdiepie has far more overall...

if i remember pewdiepie's amisha (can't spell the horror game's name) vids he gave names/bios of diffrent stuff and has a hatred of barrles. like the chopped up pigs are stuck in the "mood" has a french/russain statue thing called sparno (misspelled the name) the grunts(?) are called bros.

List updated once more....

Maybe make a jarl that is Jeb, 2nd owner of M.C and have a M.C castle.

@trehultzen831 Will do, with Notch telling about him... but the castle will take time (prob. good material for the 2.0 release)... as for the derp ring that may be harder to do but I think will a little edits to the original idea I can make it work

i like the derp ring maybe add a derp necklace that puts whoever wheres it eyes into a derp state [. ] [ '] like so

@creator20225
i'll check to see if thats possible...

yay!

How about something from Fallout? Like maybe random bandit camps have Fiends or Raiders instead of bandits. And maybe an ED-E companion! I love that little robot...

@T-Star137 I'll do some research, see what would be suitable to the mod:)
