| Big Kahunka|
Unleash the Deep Sea Gargantuar
Difficulty: Extremely hard
Big Kahunka is an achievement in Plants vs. Zombies 2. It is achieved by "unleashing" but more specifically completing Big Wave Beach - Day 16. It is worth 20 points on Game Center for iOS devices and 2,000 XP on Google Play Games for Android devices.
Its name is a portmanteau of the 1999 movie The Big Kahuna and the word "hunk," meaning a strong man, referring to the Deep Sea Gargantuar. In addition, Kahuna is an Ancient Hawaiian word, which basically means that someone excels in a given job. It has since been used in pop culture in several ways, typically described as "big". Some appearances in fiction are with the film "The Big Kahuna", as well as the "Big Kahuna Reef" games made by Reflexive Entertainment.
- It cannot be achieved by completing either Day 8 or Day 14 of Big Wave Beach, despite those levels having Deep Sea Gargantuars in them.
- This is because neither of these levels are the "Massive attack."
