French Kiss

Indeed. The original was:
"Je vous aime bien! Bon! C'est bon!"
("I like you [formal "you"]… lots! Good! Feels good!")
This was likely provided by a translation tool, so it was touched up to come across as an actual native speaker.

Literary/Cultural/Political Note:
The Very Bougie Caterpillar (page 3, panel 3) is an
extremely clever gag, which puts a Marxist spin on
The Very Hungry Caterpillar, a series of children's
books by Eric Carle.

"Bougie" is a shortened form of "bourgeoisie," an anti-
capitalist term coined by the French, who've had a soft
spot for socialism ever since the French Revolution.

Another Marxist reference occurs on page 3, panel 5:
"In order to line his pockets, the caterpillar exploited
the lower class... "
On the book cover in panel 3, the greedy caterpillar is
smoking a fat cigar, which is practically the trademark
of a self-satisfied plutocrat.

So Constance grew up reading commie lit for kids!

Very clever, indeed.

It's a very clever gag.
