Beware of the Undertoad (The Grim Adventures of Billy & Mandy)

"Beware of the Undertoad" is the second half of the sixth episode in the sixth season of The Grim Adventures of Billy & Mandy.

Plot
When Billy, Mandy, and Grim once again go to the beach, Grim warns Billy to avoid swimming too far, because the "undertoad", a frog-like creature, will try to drag him into the sea. Billy encounters the undertoad, and he barely makes it back to the beach. With the dangers of the sea averted, the guys go back home, but the undertoad is set on bringing Billy down, and he follows him to his house.

Why It Sucks

 * 1) The start is very mean-spirited, as it has Sperg and the others make fun of Billy just because he's scared to go in the water because of the undertoad. Then, Billy gets dragged by the undertoad, and Grim and Mandy never bothers or care to save him.
 * 2) Speaking of which, the undertoad's design is unoriginal and generic, as it's basically just a normal frog with an annoying voice, along with the big frog that eats Billy, Mandy, Grim and the sailor, and the wood sailor.
 * 3) * The undertoad himself is no better, as he puts Billy's bed on water, goes into Billy's school bag without his permission, insults everyone when getting on the school bus along with farting, putting half of Miss Butterbean into his mouth and even getting Billy into trouble.
 * 4) Some toilet/gross-out humor here, such as Billy eating the undertoad spitting him out through his nose along with the undertoad farting in Billy's school bag.
 * 5) Billy keeps getting blamed and told off for things that the undertoad did as mentioned above to the point where he got thrown of the bus which caused him to be late for school, sent to Principal Goodvibes' office and even grounded by his parents.
 * 6) The undertoad never felt any remorse at all for getting Billy into loads of trouble, nor did he apologize.
 * 7) Half-bad ending: Although the undertoad found his mother and sort of got his comeuppance, it just ended off with the mother toad and the son crashing the boat Billy, Mandy, and Grim were in and said "Hey Junior, that's how you bring people down".

Redeeming Qualities

 * 1) Good moral: If you love something, you must set it free.
 * 2) Half-decent ending: The undertoad finds his mother at the end, sort of gets his comeuppance, and goes back home, while Billy, Mandy, and Grim set sail on the ship with a wood sailor.

Trivia

 * In the big pile of things found near the end, Hector Con Carne from Mh:besttvshows:Evil Con Carne can be seen.
