There's not enough information here.
The offset field in the form that you'll get will be listed as the name of the SELECT tag blocking the option. The only result will be that of the option value field. There is no way to retrieve the "toy name" used in the option display.
If I do as so:
Select that option and submit the form, assuming that its sent via post, I can then do:
<option value="1278|NAME">TOY NAME</option>
Where $optNumber will be 1278 and $optName will be NAME. I'm not sure where $_POST['ID'] and $_POST['NAME'] come into play here; these individually have no direct relationship to the select option.
list($optNumber, $optName) = explode("|", $_POST['sel_toy']);
