Background Information[]
At the bottom of each puzzle lies a remark in parenthesis specifying which of the answer sheets has the solution to the particular problem.
Factoids related to real life items are included in a few sections as interesting pieces of background information to young readers:
Ferb states that the first ever website was nxocOL.cern.ch formed in late 1990, referring to the initial World Wide Web directory managed by founders CERN.
A trivia rectangle discusses the invention of the skateboards as they were originally built by bored kids in Los Angeles in the early 1950s through nailing halves from torn-out roller skates into boards. This is the common consensus on the topic, although there are arguments to an earlier inception, an uncertainty pointed out by the box itself.
Clarifications on some types of words are given in the Zany Tales introduction, with brief glances on objects, plurals, action verbs, adjectives, adverbs, vehicles, buildings, shapes, and interjections.
A substitution algorithm based on symbols is utilized in the Evil Proclamation Decipher similarly to how the A1Z26 code is applied to the Secret Code Decoder.
The catchphrase "Yes, yes I am" is alluded to in two different instances. Theme song lines "fighting a mummy", "discovering something that doesn't exist", and "driving our sister insane" are also referenced once, twice, and once, respectively, the first of which as "finding a mummy".
In the Zany Tales segment, the game's name is written with the symbol ™, playing on the common usage of the trademark license in indicating a genuine article instead of the intended protection for intellectual properties.
A few activities are reused from Game On!: Fun Stuff Activity Book, namely Platypus True or False, Perry Word Making, Surroundings Look and Find, Ferb's Noggin Nudgers, Secret Code Decoder, Unusual Pet Unscramble, Nemesis Tic-Tac-Toe, Move Word Find, Swamp Oil Maze, and Zany Tale #10: Badbeard's Treasure. Apart from those, the two Connect-a-Dots are extended retoolings of the Connect-a-Nemesis. Some old games have been slightly changed:
Surroundings Look and Find has spaces outlined to pen down the answers.
Secret Code Decoder modifies the first phrase to concern an inator rather than magic elves.
Unusual Pet Unscramble adds an anagram for "platypus" to the mix, and a joke by Buford about scrambling eggs.
Nemesis Tic-Tac-Toe incorporates eight extra spaces for gameplay.
Swamp Oil Maze attains a curved shape on the borders replacing the rectangular format.
Evil Schemes touched on in the book are the Ugly-inator, the Destruct-inator, the Ray Gun of Pure Evil, the Slow-Motion-inator, the Space-Laser-inator, the Copy-and-Paste-inator, the Woodenator, Shrinkspheria, and the Turn-Everything-Evil-inator. Doofenshmirtz Hideout-shaped Island is also brought up, as part of an encoded statement.
