Strategies
This plant is worth for 350 sun. However, as the plant's toughness increases, the Toughberry's effect decreases. Using it on 2 Wall-nuts is actually better than using it on one Tall-nut, because:

(72-5)x4=268

(144-15)x3=387

Since wall nut's health is exactly half of tall-nut's, the calculations don't match here. It is recommended that you use it on plants which have less than 100 health, because otherwise it would be underpowered.

Formulas
These are the formulas for the strength of toughened plants. H is the health of the plant. Note: If a plant is in a higher 'Plant Health' category and it's health drops down to a lower 'Plant Health' category, the formula will be the same as the higher category. e.g. If a plant's health upon planting is 350 ndb and it's health drops to 1 ndb, the formula will remain (H-55)x2. Weird, right?
