Bugdom

Bugdom is a third-person Platformer developed by Pangea Software and released in 1999. It came pre-installed on second generation iMacs. In it, you play a cute little pill-bug named Rollie McFly, who is on a quest to free the land of Bugdom from the grip of the tyrant King Thorax and his legions of ant soldiers. On the way, Rollie must fight a variety of different bug-themed enemies, find colored keys that open specific leaf doors, kick open walnuts to collect useful items, and free ladybugs from spider-web cages.

Tropes used in Bugdom include:

Airborne Mook: The flying bees. The only way to kill them is by rolling at them while they're diving down to sting you, and when there's pools of deadly honey around every corner, this is not an easy task. You can run and dodge them fairly easily, but then they just follow you all over the level, constantly buzzing in your ear, which can get intensely irritating.
Animal Stereotypes: Friendly bugs include ladybugs and dragonflies, while enemy bugs include mosquitoes, red ants, bees, roaches, spiders, flies, and slugs. The ladybugs all wear pink high-heeled shoes and makeup, the drone bees die as soon as they fire their stingers (even if they failed to hit you), and the slugs are the slowest critters in the game. And true to his name and species, Rollie has the ability to curl up in a ball for added protection. (Though he can also roll around at high speeds, which real-life woodlice only wish they could do.)
Artificial Stupidity: The spear ants will always run off to retrieve their spear, even if it means walking into a fatal substance like water or lava. And thank goodness for that, because it's the only way to get rid of the ghost ants on level 9.
Bloodless Carnage: Lots of dead bugs in this game, but no bug entrails to be seen.
Check Point: Most levels will have a couple of large drinking straws with drops of water dangling off them. You jump and knock off the water drop to get the check point.
Chest Monster: Those little red bugs. Sometimes you'll kick open a walnut, hoping for something nice like a clover or a raspberry, only to get one of these bastards chewing on your rear.
Collision Damage: Some enemies — spiders, bee grubs, slugs, caterpillars, etc — can damage you just by touching you. Possibly justified since some of them are poisonous bugs.
Cycle of Hurting: It's possible to get stuck in the landscaping, and if this happens when you're near a spear ant, you're in for a lot of stabbing. It can also happen if three or more spear ants gang up on you.
Damsel in Distress: The ladybugs.
Elite Mooks: Most ants are armed with just a spear, but some of the ones in levels 8 and 9 can fly and breathe fire.
Everything Trying to Kill You: Level 8 is a pretty harrowing experience because of this, although level 9 is arguably just as bad owing to the unkillable ghost ants.
Fake Ultimate Mook: The drone bees may look muscley and intimidating, but once they've fired their one and only stinger at you, they drop down dead. All you have to do is jump out of the way.
Final Boss: King Thorax.
Giant Foot of Stomping: In level 4.
Giant Spider: Actually, they're regular-sized spiders, but since your character is a pill-bug, they come across being human-sized.
God Save Us From the Queen: The Queen Bee, naturally. She arguably is more difficult to beat than the Final Boss.
Goomba Stomp: The bee grubs die this way. Everybody else, though, is tough enough to require one or more kicks.
Green Hill Zone: Levels 1 and 2, the Lawn.
Half-Dressed Cartoon Animal: Rollie and the mosquitoes wear sneakers, the ladybugs wear high-heeled shoes, and the boxing flies wear boxing gloves.
Hoist by His Own Petard: In level 8, there are numerous cherry bombs and dynamite sticks scattered around. There are also lots of fire-breathing ants and poisonous roaches that emit a highly flammable gas. Both enemies are very difficult/impossible to beat if you attack them head on, but if you lure them over to the bombs, they do your work for you.
Hornet Hole: The level inside the beehive as well as the setting where the queen bee boss fight takes place considering you're still inside the beehive during that boss.
Humans Are Cthulhu: Beware the giant stomping feet of doom!
Insect Gender Bender: The ants are ruled over by a king, and the beehive has a number of drone bees who act as muscley guards. On the other hand, the blood-sucking mosquitoes are stated to be all female.
Instant Kill: In level 4, if you fly too high on a dragonfly, a GIANT BAT swoops down and eats you. The fish in level 3 are a similar insta-kill.
Interchangeable Antimatter Keys: Some of the walnuts contain colored keys that open corresponding leaf doors. The keys disappear as soon as you use them, but fortunately the doors stay open.
Invincible Minor Minion: The water skeeters, slugs and caterpillars, although the latter two never waver from their prescribed routes so you're safe so long as you don't accidentally blunder into them or get impatient while walking behind one. Also, if you kill an ant on level 9, it will become an unkillable ghost ant. These are very frustrating because they can still do normal damage to you, but you can't even touch them because they're incorporeal.
Lava Pit: Which are found in...
Lethal Lava Land: The anthill.
Level in Boss Clothing: Level 5 is completed by destroying the beehive at its centre, identical to how Queen Bee and King Ant are completed. The beehive cannot actually attack you, however, and the threats in the level consist of flying bees and various terrain hazards on the ground.
Lily Pad Platform
Live Item: The buddy-bug, whom you obtain via walnut just like the inanimate powerups and who acts as a long-range missile.
Minus World: If you jump at a wall at just the proper angle, you'll end up in a weird mirror-land where all the landscaping is the same but all the walnuts and enemies are eerily absent. If you walk far enough, you'll end up in a white void.
Mook Bouncer: The fireflies, except they don't teleport you — they pick you up and carry you off to somewhere you absolutely do not want to be.
1-Up: Like everything else, you get them from walnuts.
Platformer: The whole game, but especially levels 6 and 9.
Power-Up: Raspberries restore your health, mushrooms restore your rolling time, and clovers increase your score.
Super Drowning Skills: Averted — Rollie can swim just fine, and he can even jump across the surface of the water.
Triumphant Reprise: The menu screen music has a triumphant reprise in the winning cutscene.
