GOD. The double baby is supposed to be a DOUBLE SUNFLOWER so WHY making it drop 2x faster but one heart is a good idea? (Double sunflowers drop 2x more sun but a bit slower)
'Cause(if you don't know) in late stages there is a limit to only 6 hearts store, so WHY player would want to use slow speed double-hearting baby, that constantly overflows the limit?!(plus cost more and recharges longer than single one, so much more difficult to fill loses after big waves)
Twin-CHADs "seems cool" only on first stages, when there is no heart limit and OP enemies.
