Also, I found an interesting case about Split Peas! In Wild West - Day 8, if the Gargantuar is trying to crush an available plant (plant planted before), then we plant a Split Pea behind it, that Gargantuar will take all peas!

It means Split Pea's Boost can kill instantly a single Gargantuar.

This is the same as Starfruit's case, too!
