Tantor and Terk accompany the Professor on an expedition to study giant flora and their clumsiness almost ends in disaster. Tantor wants to confess but Terk prefers covering up the truth. Professor Porter does manage to collect some plant liquid from the giant flowers, which Terk promptly spills onto some beetles making them grow to gigantic proportions. Terk still tries to hide her and Tantor's involvement. It's not long before the beetles are on a rampage of destruction.
