Trophy

Trophy’s are rewards for beating bosses in PSE. Defeating a X boss will award in the trophy being "upgraded".

Sand Noob
The trophy is a Sand Noob Seed, which looks likes a normal yellow head, and some sand around it. It reads:

"This is the Sand Noob Seed, which is acquired from defeating a Sand Noob. the Sand Noob is a plant-like entity that is always burrowing into the ground, acquiring energy from a certain, mysterious energy that elevators like this leave behind upon teleporting away. They are generally obedient to their owner, but the wild ones have free will, and will not hesitate to randomly attack anyone who gets anywhere close to them. It should also be noted that sand noobs are sentient and can talk normally. Their abilities can range from removing their eyes from the ground to attack in many different ways, to summoning sandstorms in the area and bending it to their will. Without eyes, they can still sense your presence."

Sand Noob X upgrade
The upgrade adds a crown to the Sand Noob Seed, it reads:

"Sand Noobs aren’t very bright, for they can easily fall to any weapon. However there exist another kind of sand noob that poses a greater threat; the Chaos Sand Noob. These are sand noobs that have emerged while having a crown. This crown, when applied, boosts its ego rapidly, making it significantly stronger. Whoever put a crown on the head of the chaos sand noob you fought is a complete mystery but we theorize that this may be the doing of Narby and Narby."

Rogue Killbot
The trophy shows a yellow neon rocket, it reads:

"This rocket is what is commonly fired from certain special killbots, including the rogue killbot who was fought. It appears to be primarily composed of the same element that can be used for an ingredient for certain potions. Killbots are rare machines, designed to make an obstacle more challenging. This killbot went rogue due to Narby bringing it out of its original place. The killbot started to malfunction, and Narby threw it into the depths of one of her own floors; the Neon Dimension. There, the killbot slowly aligned to the location and spent 10 years defeating players who challenge it, up until now."

Rogue Killbot X upgrade
The upgrade adds red neon lines to the rocket, it reads:

"If you ever thought that a killbot was bad enough; the Advanced Killbot poses a significantly greater challenge. This is an upgrade that is applied to the killbot in order to give it more devastating attacks."

Noob Ghost Clone
This trophy is unlike all others, instead of being inside a trophy thing its just a small brick lying on the ground and is not lined up like the others, most likely due to how easy the boss is. It reads:

"Noob Ghost has many extraordinary abilities, including the ability to clone himself infinitely. His clones usually stick close to him, but sometimes he leads them away to seperate floors. These clones are weaker, and they spawn even weaker clones. The clone you defeated gave you a tiny brick. Very amazing."

Noob Ghost
The trophy is a 1x0.5x2 grey brick, it reads:

"The Noob Ghost is a mysterious spirit that has been haunting a floor for an extremely long time. He is not harmful, but in order for him to help, you must challenge him to a battle. He only challenges those who have proven to be strong enough to fight him. When all is done, he will assist you in certain things, and is a very powerful ally in certain ways. He gave you a 1x0.5x2 brick for your victory."

Noob Ghost X upgrade
It adds a golden brick to the top of the grey brick, it reads:

"Noob Ghost X is the significantly harder variant of Noob Ghost, and is very overwelming for many. He has very hard attacks and hits hard. He gave you a golden 1x0.5x2 brick on top of the other for your victory."

Aquatic Noob
This trophy is identic to Sand Noob's, except the seed is blue and its underwater, it reads:

"This is the Aquatic Noob Seed, which is acquired from defeating an Aquatic Noob. Being close relative to the Sand Noob, they seemingly have a close connections. The reason for entering ocean waters are still unknown..."

Aquatic Noob X upgrade
Its identic to Sand Noob X's upgrade, except the crown is entirely blue, it reads:

"Jupiter please come back and fill this in.", which means its just a placeholder.

Trívia

 * Noob Ghost Clone's trophy is the only trophy that cannot be upgrade, due to it not having a X form.
 * Defeating a admin-only boss will not result in a upgrade.
 * The trophies and the bosses are likely a reference to Terraria developed by Re-Logic.
