Does g_list_remove() compare the pointer or the string which the pointer
points to when searching for the appropriate entry?  In other words, do I
need to pass in the original
variable which I used in the g_list_append() to create the list?  (That
didn't sound to clear either)

The only thing I can think of, is that the pointer that gtk_entry_get_text
returns to the text isn't the same as the pointer that is stored in the
list.
It might be possible to loop through the list comparing doing strcmp
(Toys->data, selectedToy) on it, and then deleting the one that matches,
although this seems a long winded (and potentially very time consuming) way
of doing it.
