SQL & PL/SQL :: Creation Of A Object Relational Database

i am working on a project that requires the creation of a object relational database. A number of different methods are required in order to insert different toy types into the appropriate toy related Object Table(s). Within this there will be the following fields:

Toy_name
Cost
Age_Range
rdy_allocation

and then some more specific information. The specific information for each toy is:

Toy_Type.
The toy_type can be electronic, game, or wooden.
For electronic I need to store Battery_Type and Number_of_Batteries.
For type Game, I need to store, Type, this could card_game, board_game or other_game.
For type wooden, I need to store Painted(Y/N).

The toys are requested by a child and created by elfs. This information also needs to be recorded but im more concerned with the creation of the toy class itself first. Now this was my first attempt at the solution but I cant seem to link the specific toy information into the same table. Will i have to create three separate tables then link them together?:

DROP TABLE TOY_OBJTAB;
DROP TYPE electronic_toy;
DROP TYPE wooden_toy;
DROP TYPE board_toy;
DROP TYPE toy_typ;
