To complete the game completely it is not very hard and not very long. However the game remains simpler and more fun with a friend!
Important to know
If you reached the top of the island and get caught(with your friend in coop) you will lose your crown. But no worries because you will gain new objects that will facilitate the ascent.

Royal Appetite
Win a crown by reaching the top of the island for the first time.

--
Kingdom
Win a second crown by reaching the top for the secoond time in the same party.

--
Impossuble
Win the game by reaching the top of the island for the third time in the party.

Stuffed!
You just have to manage to get 30000 points by counting all your games, you should receive it only by playing
--
Give me your Chippies!
This one also has to activate itself in the course of your game, to obtain it you must prosecute an npc (other than the police) during half of the map
--
Inchompetence
Same for this one, playing should be sufficient. 4 guards must be chasing you.

--
Culinary Exploration
Already a little more complex, you need to visit all areas of the island at least once. My advice is not to go up but on the sides when unlocking areas and gradually climb.
--
Triple Hot Dog
In the game, you will unlock items by getting caught trying to get to the end of the island . One of these items is a bomb who can knock out your chasers. You just need to knock out three of them at the same time.
--
Mozarella and Toma-thief
In some areas there are big dishes that you can eat staying close to these, just eat the mozarella salad.
--
Gigantic Nothing'
Same here but it’s a pizza.

--
Fast 2 Delicious
As said above, this is one of the unlockable items that you simply need to use.

--
Smoky Flavour
Idem.

--
Big Haul
For this one you just have to play but you will surely have to replay even after winning. It is necessary to unlock all the objects, there is 15 to unlock.

Zeppolicious
