Well, actually there are no peas in the third string of letters below, but it made a good rhyme and there are three other vegetables to find.
The first string of letters below intermingles the letters of three different trees. The letters appear in the correct order for each tree, but the three have been randomly intermingled.
The second string intermingles the names of three types of tea, and the third string three different vegetables.
