I can't decide if this is brilliant parenting or terrible parenting.

Oh dang! I didn't even notice that.

"Come on! try a glass of beet juice! It's healthy and good for you!"
"Alright ALRIGHT!" PFFFFFFFFFFT "Oh god, that's horrible."
"..........also it stains horribly."
"Great."

Good thing he already has the neck-brace/Cone-Of-Shame.

Also noteworthy that frogs aren't very likely to drown in this situation; they're quite capable of just floating with their heads above water while lying still and resting, so that's probably not why the 3rd frog wants up on the floating lid.

What an unusually decorative manhole cover. Is that in Toronto?

Hmm... well, I would probably want to cover the seats first, but maybe not the worst way to clean out the floors and dusty dashboards, particularly if he recently had a lot of people with muddy shoes who didn't wipe their feet getting in, or some worse abnormal mess-makers, like kids throwing up in his car, or dogs who didn't hold their bowels until the park. Sometimes extraordinary measures are necessary.

On the other hand, given that the hood and roof of his car have been replaced and not painted to match, maybe he really IS just careless?

While the Titanic comparison is amusing, does everyone understand what's happening there? Smaller male frog is mounted on a larger female for mating, while another frog (might even be female by the size) is trying to climb up, but the male kicks (her?) off the "bed"... repeatedly.

"Piss off! We are NOT doing a threesome!"

Nah, he actually looks pretty active here.
His biggest problem is probably his parents overfeeding him sugar.
