[SMARTY] foreach and multidimensional arrays

H'lo folks...

Apologies if this has been covered earlier, I had no luck searching for 
it... although it could be I'm not phrasing things correctly.

I have a multidimensional array that looks basically like this:
$foo = array(
        bar => array (
                a => array ( 'dog' , 'cat' , 'etc' )
        )
)

The template I'm trying to jam this structure into looks something like this:
{ foreach key=type from=$foo item=pulldowns }
        ...snip some html here...
        { foreach key=pulldown from=$pulldowns item=values }
                <select name="blah">
                <option> any { $pulldown }</option>
                { html_options options=$values }
                </select>
        { /foreach }
{ /foreach }

Net result is supposed to be a set of pulldowns ('a', with values of 'dog' 
, 'cat' , 'etc') for each of the supplied types ('bar'). What's happening 
is that the values of the last array, the non-associative one, are being 
output twice... once with keys of [ 0 ... n ] and then again with the value 
of $pulldown. Although unexpected, I understand why the "extra" values are 
showing up... but my perl background is a source of continual surprise when 
I'm working with what I think of as hashes.

Short version... how do I suppress the values that are due to the numeric 
keys? Or, for bonus points, vice versa? ;)

Appreciate any direction/input you can provide...
