Leef Apple Glyn Slitheen-Blathereen

Leef Apple Glyn Slitheen-Blathereen was a member of the Slitheen-Blathereen family and the wife of Tree. Both she and Tree looked down on the Blathereen side of their family, and were addicted to eating Rakweed.

In 2009 they hatched a plan to spread the Rakweed across Earth and gain huge profit,landing their ship in Antarctica and using it as a base.They put their scheme into motion by giving a Rakweed plant as a gift to Sarah Jane Smith, gaining her trust by first foiling a Slitheen plan to destroy Earth and posing as bounty hunters.The Rakweed then started to infect London, including Sarah Jane's son, Luke. Enraged by this,Sarah Jane teleported herself to the ship and threatened her and Tree with a water gun filled with Vinegar. Leef tricked Sarah Jane into letting down her guard by feigning ignorance of the Rakweed's effects, and having Tree falsify a removal of the plant. When Sarah Jane lowered her weapon, Leef was able to restrain her. However, Sarah Jane later managed to escape and find a way to destroy the Rakweed and stop the infection. Leef and Tree then transported themselves to Sarah Jane's attic, and tried to kill her and her friends. In retalliation, Sarah Jane had Mr Smith replicate the sound of an alarm bell to destroy the Rakweed in Leef and Tree's stomachs. This caused a massive methane gas build up which killed them both. Clyde refered this as farting themselves to death. (SJA: The Gift)
