Each [spell=385181] summon 6 [npc=195399], and achievement need 10. CC such like [spell=102359][spell=116844] is very useful.

0:09 First [spell=385181], bring Goliath leave the [npc=195399]s, put [npc=195399] to a corner to avoid aoe damage.
0:20 First [spell=385555], dont let Goliath eat anything because achievement need you keep it [spell=385743] when eat.
0:50 Second [spell=385181], start bring all enemy together.
1:00 [spell=385442], bring [npc=195399] to Goliath if still not together because it wont move when casting, and next [spell=385555] will cast 2 sec later, you wont have time to move Goliath.
1:07 Second [spell=385555], let Goliath eat.

Easy to Solo in TWW.

-Engage boss and take him to 50% HP

-Kite him around and let 10 (or more to be safe) swoglets spawn

-When he is about to cast gulp (there will be a green ring around him) Run at him taking the swoglets with you into the circle.

-He will eat you and the swoglets (they look like they just die, but this is them being eaten)

-Kill the boss and get the achievement.

Hope this helps.

Criteria:
Defeat the Gulping Goliath after forcing it to become Hangry and devour 10 Curious Swoglets in Halls of Infusion on Mythic difficulty.

Strategy:
This achievement requires some coordination and is easier to do for groups that have long lasting AoE CC abilities such as Sigil of Misery and Mass Entanglement. During the encounter, the boss will cast Overpowering Croak, causing cave-ins that spawn swoglets. You will need at least two waves of swoglets to complete the achievement. Your group should stack up so that the cave-ins are close to each other. This will make sure that the swoglets spawn close enough to be gathered and CC'd. Once the second wave is spawned and CC’d, the tank will want to drag the boss over to the swoglets and let him gulp them down.

One important note: The boss must be Hangry, and in order to achieve this, do not let him consume anything during his first Gulp cast. You should be able to get all 10 sowglets before the second Gulp cast. Once the boss has been made Hangry and has consumed 10 swoglets, defeat him as normal.
