The Torah warns us that we should not accumulate too many Dr. Seuss books, as it states in Deuteronomy 17:16

רַק, לֹא-יַרְבֶּה-לּוֹ סוּסִים

One should not amass Seusses

Being that one should only get a minimal amount of Dr. Seuss books, I was wondering which ones are recommended to get. Also, which ones should be avoided?
Please bring sources from Scripture or Rabbinic writings.

This question is Purim Torah and is not intended to be taken completely seriously. See the Purim Torah policy.

Oh, the Thinks You Can Think! is obviously a must-have.

Its philosophy is very much in line with that of Mishlei 19:21:

רַבּוֹת מַחֲשָׁבוֹת בְּלֶב־אִישׁ

Many thoughts are in a man's mind.

Green Eggs and Ham would be a great choice for teaching children about brachot. Take this Mishnah Berurah (205:9), which explains when to bless, and on what.

בהם ירקות וכו' - ר"ל שרוצה לגמוע המים לבד דאלו אם אוכלן עם הירק אין שייך שום ברכה על המים דנעשין טפלה לירק:

With Ham and Greens etc. - Meaning to say, that he wants to swallow only the ham, for if he would eat it together with the green, no Bracha would be necessary on the ham because it becomes secondary to the green.

Sorry, but this answer is an anti-recommendation: there is no apparent evidence that The Cat in the Hat is authentically part of Jewish tradition.

דע את עצמך is a Seuss classic, which is sold in many Jewish book stores.

Any self-respecting Kabbalist needs a copy of Yertle the Turtle, which hints at the deep mysteries taught in Tikkunei Zohar 147b.

In Tikkunei Zohar’s discussion of the properties of a stack of turtles, we learn:

ומאן דידע שיעור קומה דילה איהו ירתעל מאד אתי

He who knows the measure of its height is Yertle, [the one who eventually] to the mud comes.

(It is of course no surprise that Kabbalah discusses stacks of turtles, an ancient meditation on the nature of infinite regress.)

The Lorax teaches the dangers of non-differentiated clothing. Thneeds are the embodiment of sin that Lorax the Prophet speaks out against.

They encourage displacement of workers in favor of the factory-owner's family, a diaspora of Bar-ba-loots who leave in search of kosher foods to eat, and devastation of the land.

While his use of the Truffula tree was not for food, the factory owner has removed fruits from the Bar-ba-loot population, therefore violating Torah.

When you besiege a city for many days to wage war against it to
capture it, you shall not destroy its trees by wielding an ax against
them, for you may eat from them, but you shall not cut them down. Is
the tree of the field a man, to go into the siege before you? However,
a tree you know is not a food tree, you may destroy and cut down, and
you shall build bulwarks against the city that makes war with you,
until its submission. (Deuteronomy 20:19-20)

Yet, there is teshuva.

Unless someone like you cares a whole awful lot, nothing is going to
get better. It's not.

The factory owner shares the story of his destructive ways and passes the means for reclaiming the land to the next generation.
