Invi-nut

The Invi-nut is an upgrade of the Infi-nut in Plants vs. Zombies: The Final Showdown that has more health and is resilient to instant-kill attacks.

Where the Infi-nut has less health than a regular Wall-nut, the Invi-nut upgrades it to have the same health as a Wall-nut, alongside a heavy resistance to attacks such as smashes from Gargantuars, taking six smashes or equivalent attacks.

Unlike the Infi-nut, the projector is also immune to most of these attacks, meaning it can only be fully destroyed by vehicles crushing it, Bungees stealing it, or otherwise being removed from the screen (E.G. Excavators or Mecha-Football Zombies) Gargantuars will walk past once the nut is destroyed, where they would smash the Infi-nut even then.

It is unlocked by purchasing it from Burt's Bits & Bobs for $15,000, after unlocking Infi-nut.

Origin
Its name is based on Infi-nut, however changing "infi" to "invi", meaning invincible.

Appearance
Similar to an Infi-nut, but a bright purple in colour (similar to Garg Prime lasers) and possessing a far more determined, almost angry expression.

Almanac Entry
Invi-nut

A nut that can regenerate health and is resistant to powerful attacks.

Toughness: high

Self-healing rate: max health after 15 seconds without damage

Special: immune to lasers, blocks laser-based attacks, resistant to instant kills

Plant Food effect: generates two forcefields, protecting every row

Must be planted on Infi-nuts

Invi-nut will always, ALWAYS spend every opportunity boasting about how he's completely invincible, even though he's not. It gets so annoying that sometimes the other plants WANT him to get smashed to pieces.

Cost: 75

Recharge: very slow

Plant Food
When fed with Plant Food, Invi-nut projects two forcefields in the two spaces in front, unlike Infi-nut's singular forcefield.

Strategies
Invi-nut has similar utility to Infi-nuts, as it has low health for its cost, but regenerates that health after a period without taking damage. However, unlike Infi-nut, it isn't ruined by Gargantuars, or most other instant-kill zombies. Such attacks cause rather low damage to Invi-nut, and cannot destroy its projector like they could with Infi-nut. This utility as a regenerative wall even against Gargantuars is extraordinarily useful, but for its recharge timer and cost of 150, setting it up in every row isn't necessarily easy.

Invi-nut doesn't work well against all instant-kill zombies however. Vehicles will still cause damage very rapidly and can crush the projector, while Bungees can steal it. However, these vulnerabilites can be compensated for using Umbrella Leaves for Bungees, and E.M.Peaches or EMPeashooters for vehicles.
