Adventures of Lolo is a trilogy of Block Puzzle games released on the NES, and part of Hal Laboratory's Eggerland series (which began its life in Japan on the MSX computer system). A beast known as the Great Devil (King Egger) has kidnapped Princess Lala and, in typical bad guy fashion, imprisoned her at the top of a Death Trap and monster-laden tower. It's usually up to Lolo to solve the puzzles with and climb to the top and rescue her. The third game in the trilogy allows you to play as either character and, in the final four levels, be required to rescue the character you sent to finish Level 13.Interestingly, despite Hal being a subsidiary of Nintendo, Hal owns the Lolo series independently and completely, unlike some of their more popular titles.
The Lolo games provide examples of:
Baleful Polymorph: With Magic Shots, Lolo can zap enemies and turn them into eggs to be used for various purposes.
Collision Damage: Only Armas and Skulls and sometimes Don Medusae (if you step halfway into one's patrol path). All other enemies either have specific attacks or can't kill you on their own. You can even push against the dangerous ones without harm if they are trapped or retreating; the kill only happens when the enemy decides to move onto Lolo/Lala.
Difficulty By Region: The Japanese versions of Adventures of Lolo 2 and III (released as Adventures of Lolo and Adventures of Lolo II since the American Adventures of Lolo was not released in Japan) have completely different, harder puzzles. Justified as the American version contained puzzles copied from older Eggerland games.
Disc One Final Dungeon: Adventures of Lolo III pulls this twice. After beating every level except King Egger's castle, the protagonists get on a boat to get there...which then gets shot down and they end up underwater, where they have to clear 4 more levels to sink the castle so that they can reach it. After going through the castle, whoever the player is controlling gets captured and the other protagonist chases after them through an underground passage to Egger's real castle, which requires another three levels to access.
Early-Installment Weirdness: The first game, Eggerland Mystery, is the only one to contain Diamond Framers instead of Heart Framers, a "Type B" gameplay mode in which each puzzle is timed, or points. Some monsters (Leeper, Don Medusa, and Rocky) and some terrains (trees, flowerbeds, sand, and lava) would not appear until the second game, and neither would the hammer power-up; instead, "Create Emerald Framer" was a standard power-up.
Expy: Characters named Lololo and Lalala (who look like Lolo and Lala, only smaller) appear as minor antagonists in some Kirby games (another series made by Hal Laboratory), and as his friends in the anime series Kirby: Right Back At Ya!.
Eye Beams: Medusa, who'll petrify and zap Lolo with them if he walks within her field of linear vision. Don Medusa, who has the same ability (but is more dangerous because he can move back and forth), uses knives instead. Lolo doesn't even have to be looking at them for the eye beams to work.
The Goomba: Snakey is often the first enemy Lolo comes across in his journey and has no abilities but spinning in place to follow Lolo's progress.
Guide Dang It: If you block an enemy's spawn point with something other than yourself (which will just get you killed,) they'll get Tele Fragged when they respawn. But certain enemies will just respawn in a preset location instead. Certain puzzles require you to pull off the latter. Good luck finding out when (it doesn't help that the games don't even tell you you can do this until the third one.)
Hard Levels, Easy Bosses: Whenever there's an actual boss fight in the series, it's usually just a "Dodge giant enemy moving in a preset pattern while shooting him a bajillion times" that isn't really challenging at all once you know the pattern.
Though if you lay a bridge on top of lava, it'll eventually catch on fire and disappear.
Level Editor: Featured in three of the Japan-only releases, the one in Revival! Eggerland being the most detailed featured, while Departure to Creation has features accurate to the NES games.
Meaningless Lives: Running out of lives in Adventures of Lolo forced the player to start the entire floor over again. The second game, though, let the player continue from the room they were in, effectively making lives meaningless other than showing them the password screen (the third game does away with lives altogether.)
Nintendo Hard: You better go into Adventures of Lolo III not only knowing every single quirk of the engine (because you'll be using all of them) but having mastered the controls to finish puzzles as fast as humanly possible.
Press X to Die: Select is a suicide button in case you get stuck and there's no way for you to die on the level.
Purely Aesthetic Gender: In the third game, you have the option of playing as either Lolo or Lala. Gameplay-wise, there is absolutely no difference between them.
Regional Bonus: The Japanese version of Adventures of Lolo for the Game Boy had only fifty levels. The European version increased this to one hundred forty-four, and added a tutorial and Super Game Boy support.
Save the Princess: The first two games. The third game potentially averts this if you go into the Hopeless Boss Fight with King Egger as Lolo, which causes him to get captured instead.
Sleepyhead: Leeper is initially a very spry-looking creature, but it spontaneously falls asleep upon coming into contact with Lolo. It is such a Deep Sleep that Magic Shots no longer affect it, so Leeper can never be moved again without a Puzzle Reset.
Conversely, Gol and Skull appear to be asleep until they are instantly awakened by collecting the last Heart Framer.
Spell My Name with an S: The armadillo enemies have been referred to as Alma, Arma, and Armma. Lolo and Lala has also been referred to as Roro and Rara in-game before, but this could simply be a case of l and r mixups.
Super Drowning Skills: Lolo and Lala can float on rivers using eggs, but if they should sink while one is still riding on them, they'll die instantly.
Super-Persistent Predator: Alma. Once she gets rolling, she'll chase you throughout the level until you stop on a flower bed, the only other terrain beside water/lava where she can't follow you.
Taken for Granite: Happens to the people of Lolo and Lala's kingdom in the third game, prompting the two to set out on their adventure.
Temporary Platform: Eggs in still water and bridges over lava disappear after a few seconds, and Adventures of Lolo III introduces bridges that crumble away after being stepped over twice.
Trial-and-Error Gameplay: The game does not disclose to players which Heart Framers contain Magic Shots until they are collected, how many Heart Framers activate each Power Option (until the player is one Heart Framer away from receiving one), the number and locations of alternate Respawn Points, or (until the Windows games) where water has currents in what direction. Sometimes it is essential to know this information from the beginning of a puzzle. The first labyrinth-based game also has rooms with multiple entrances that become Unwinnable by Design if Lolo chooses the wrong entrance.
Updated Re-release: Revival! Eggerland was Eggerland for Windows 95 updated to run on Windows 98 and ME.
Vacuum Mouth: Adventures of Lolo III introduces Moby, a small whale that opens its mouth to suck Lolo/Lala from across the room towards itself when in its line of sight.
Variable Mix: Adventures of Lolo for the Game Boy (European version only) had some levels in which the BGM changed depending on which direction Lolo was facing and whether or not he was standing on flowers.
Video Game Remake: Eggerland 2 for the MSX 2 was remade for the Famicom Disk System as Eggerland, featuring redone graphics and sound, new levels, save files, and a confrontation with King Egger at the end.
