Call of Duty: Black Ops III

To unlock this one you have to get from bubble gum distributors spread over the map the 5 Gobble Gum from your current pack. The gum from the distributors are random, cost 500$ each and you cant get more than one per round. In addition to the active distributors are moving over the map like mystery box.
Hence as soon as you encounter a distributor working get a gum.
You just need to get the gum from the distributor, you do not have to use it !

Off course, as pointed out by MikeProcurator, you have to do it during one game !

Trick from https://www.trueachievements.com/FunK+Kaleb.htm : All the machines will become active during firesales (all gobblegums) and price is reduced to 10 points could be worth adding.

Update 1.08, April 2016 : Now all the Gobblegum machines are always working and you can get more than 1 gobblegum per round but the 2nd and 3rd Ggum are very expensive. So stay in the staring area and stick to 1 Ggum per round and you should get it by round 5 or 6.

(Note: This achievement is unattainable on The Giant and must be done on Shadows of Evil, thanks for the commenters to clarify this information for me.)

This is a fairy easy achievement based upon the idea of consuming each of every Gobble Gum you have equipped. While not necessary, to use these in your pack, it's easier to do with the following Gums in your pack:

1.) Always Done Swiftly
2.) Lucky Crit
3.) Stock Option
4.) Anywhere But Here
5.) Alchemical Antithesis

You might not have all of these unlocked depending on your level. That's fine, just try to use the ones that don't last 3 rounds or have a long time limit, the real goal here is to use the gum immediately as you get it and get a new one next round.

It's technically easier to do this going for the drop-oriented gums and various Mega gums, because they are used instantly and don't typically last for multiple rounds. However, I don't think being wasteful is necessary to achieve this, but it would be faster if you want to use up those Mega gums by utilizing the Mega gums.

You can use a gumball machine a few times before it will relocate to another position on the map. The machines are scattered around the maps and usually located briefly after a door. Basically, just use one every round, pop the gum, and by round 5 or so (if you are lucky) you should have all of them popped, but you should have it guaranteed by round 10 before it starts to get competitive. Just be sure to save crawlers or one running zombie as you open up doors and use the gumball machines.

Currently due to the new zombie DLC out on May 16th (PS4) 1 gum ball is free at the start of each round.

This makes a mockery of this achievement.

This lasts for 1 week - Do it now!

EDIT: now every round always the first gum is free. So you can get this by round 6
