The main character has a gauntlet or a similar gadget in his arm that summons different creatures either for combat or just as companions, and also a yo-yo that he uses in combat and infuses it with the power of the summoned creatures.
To activate the animal's powers he ate food that shared similarities with the animal in question. For example, to activate a cubic-shaped bird's powers he ate a marshmallow. He used chopsticks so it might have been from an Asian country.
The sidekick (a girl if I remember correctly) has another gadget that she uses to collect artifacts that they encounter on their journey (either an accordion or a book).
The names of the creatures might have been awfully translated from the original version but in the version I watched it in (Arabic) it goes something like: booboo deedee....
It aired on MBC3 somewhere between 2005 and 2012.
