Skylanders: Lost Islands (PetStarPlanet's version)

Skylanders: Lost Islands is a mobile app by Activision. This is a fanon version of the game, following PetStarPlanet's timeline, that is almost the same as the real version, but with updates after May 2015.

Note: In order to understand most of the page, it is recommended that you own the actual Skylanders: Lost Islands app.

May 2015
Not much is different, but the only fanon update is that the Life Sanctum became permanently available for those who didn't already have it (assuming it didn't actually happen).

June 2015
The Lost Islands finally got rid of their Easter look and got their regular look.

A completely new Beach Island was added to the right of the Kingdom. The Beach Island also came with the Light Sanctuary and its unique clutter, shells.

June 2015 had a summer Alter Ego called Sunny Spotlight, who was also the first Light Alter Ego.

Gnarly Barkley was added to the available Skylanders and King Cobra Cadabra became available to be bought for gems (and every other Skylander that is currently only able to be toy linked). Tidal Wave Gill Grunt and Hog Wild Fryno became available.

New Light and Dark elemental adventures were added. The new Light adventures are Telescope Towers (30 min), Skyhighlands (4 h) and Sunscraper Spire (8 h). The new Dark adventures are Mystic Mill (30 min), Monster Marsh (4 h) and Midnight Museum (8 h) for the Dark element Skylanders. A Trap Master exclusive Adventure called Soda Springs (4 h) was also added.

New villains were introduced, which were Bruiser Cruiser (Tech), Lob Goblin (Light), Fisticuffs (Dark) and Bad Juju (Air). Bruiser Cruiser's special ability is that six trolls escape rather than the typical 3, and his effect lasts for 12 hours. Lob Goblin unlocks a temporary new Adventure called Nightmare Express which only takes 10 seconds and gives big rewards but costs a lot of energy compared to other short adventures. His effect lasts for 8 minutes. Fisticuffs makes it possible for special Evilikin Camps to appear. Those camps give way more bonus than Troll Camps and Sheep Mobs, and can be cleared instantly even if the player doesn't have Cape Girl. His effect lasts for 2 days. Bad Juju greatly increases the bonus of Evilized Sugarbats and her effect lasts for 1 day and 12 hours.

New beach items became available in the store.

Gourmet Gusto's house became permanently available (like the previous Skylanders' houses became in May) as well as the Bird House and the previously unavailable companions (including Diggs), which Activision forgot to make available in May. Sunny Spotlight's house was introduced. At first, it was a Gem Pack exclusive, but at the end of the month, it became permanently available. The Air Sanctuary also became permanently available for those who didn't already have it.

July 2015
Summer Nothing to see here... trolls started to appear.

Fireworks Zook was on sale for only 600 Gems from July 4 to July 5 due to a special 4th of July weekend sale. Besides that, the fireworks decoration was cheaper as well.

The new Alter Ego was Exploding Fire Kraken, which is a 4th of July counterpart of Fire Kraken.

A new update made it possible for every kind of clutter to reappear, including rocks.

A new villain called Mab Lobs (Tech) was added. He halves the energy cost of everything that costs energy except Sanctuaries. His effect lasts for 2 hours.

Bomb Shell unlocks the adventure Chef Zeppelin which takes 5 minutes (without having time boosts), but gives more bonus than Nightmare Express. His effects last for 8 hours. Chompy increases the chances of Chompy Pods appearing and Chompies coming out of Chompy Pods. His effects last for one day and 12 hours. Smoke Scream increases the chances of villains that affect clearing invaders appearing. His effects last for 2 days.

In around mid-October, the Lost Islands got the Halloween look (same as 2014) and Halloween Nothing to see here... trolls started to appear until the end of October.

The Lost Islands got a new Spooky Island with a Dark Sanctuary and its unique clutter, spider webbed skulls.

After the release of Skylanders: Teamwork, a new feature known as the Core Bombs was added. Any two Core Skylanders of the same element can destroy them together for a Gem bonus and Hero Points for both Skylanders. A Teamwork House was also added.

Trivia

 * The 8 islands that were added in 2015-2016 don't have the usual green grass (or white snow in winter).
 * Half of the 8 islands are season based.
 * When the Teamwork features were originally added, it was impossible for Light and Dark element Skylanders to use them due to the elements only having one Core each.
