There were three things shown:
1) Fiery Blowhog - Pikmin - trophy
(Picture taken by IsmaR)
People were arguing this is a Chao from the Sonic series.
I think it's clearly a Fiery Blowhog standing on two legs (he make this before spying fire). A regular enemy of the Pikmin series.
2) Sir Kibble - Kirby - trophy
That's Sir Kibble. A regular enemy of the Kirby series. (But he can also be a party member)
3) Boxy - Kirby - sticker
Boxy is a boss in the Kirby series.
Next two pictures:
4) Chain Chomp - Mario - trophy
It's clearly a Chain Chop from the Mario series.
I hope that reach for information...
5) Zoda - F-Zero - trophy
Don't know much about him, but he looks like he would be naked >_>
6) Phantom Ganon - Zelda - sticker
First boss for adult Link in OoT. Most of us know him
7) Rabbit ears (how is it called oO) - Zelda - trophy
Item from Melee/Brawl
8) Bow - Zelda or Kid Icarus - sticker
Ignore number one and look on the sticker. It's a bow....
9) Tortimer - Animal Crossing - trophy
He is the mayor of every town in AC.
10) R.O.B. - StarFox - trophy
It's the most likely choice for this trophy.
11) Dragoon - Kirby (Air Ride) - trophy
It seems to be Dragoon. A legendary ride from Kirby Air Ride.
Jambre discovered this. Thank you!
12) Peggy&Pelly - Animal Crossing - trophy
They are working in the city hall. It's clear they are Peggy and Pelly.
The last picture
13) Medli - Zelda (WindWaker) -trophy
She is one of the more important characters from WindWaker.
I'm too lazy to write about her now, sry.
14) Tortimer - Animal Crossing - trophy
Look at 9
15) Bob-omb - Mario - trophy
I hope everybody knows this item from Melee/Brawl/SSB64.
16) TP-Link - Zelda (TP) - sticker
....
17) Mach Rider - Mach Rider - sticker
He is a driver from a futuristic driving video game.
18) Dr. Samselt - Animal Crossing - sticker
He's teaching you mimic in Animal Crossing. You can identify him. Nintendo was too lazy and they are taking normal artwork for stickers.
It's this one:
____
I hope this was neccesary and helped a lot.
Still need help for the trophys/stickers I couldn't recognize.
